Explanation of Change

Two fixes for document attachment handling (.docx, .pdf, etc.):

  1. isReportMessageAttachment: For document attachment-only messages, message.text is the filename (e.g., test.docx) rather than [Attachment] (which images use). The function now detects these by matching message.text against the data-name attribute in the HTML. Also, for optimistic messages, the translationKey is now trusted as the authoritative signal for attachment-only — it's only set when isAttachmentOnly is true, so the redundant text check is removed.

  2. canEditReportAction: The attachment flags check is separated so that isAttachmentOnly always blocks editing (regardless of optimistic status), while isAttachmentWithText only blocks editing when the action is optimistic. Previously both flags were grouped under the same optimistic guard, meaning attachment-only messages could become editable after server confirmation if isReportMessageAttachment failed to detect them.

Tests

Test matrix (2 action types x 4 attachment types = 8 cases):

Image Video PDF .docx
Attachment-only Styled correctly, not editable Styled correctly, not editable Styled correctly, not editable Styled correctly, not editable
Attachment+text Text shown in LHN, editable after sync Text shown in LHN, editable after sync Text shown in LHN, editable after sync Text shown in LHN, editable after sync
  1. Open a chat
  2. Upload a .docx file (attachment-only, no text)
  3. Verify the attachment renders with proper border/styling (AttachmentCommentFragment, not TextCommentFragment)
  4. Long press the .docx attachment and verify "Edit comment" is NOT shown
  5. Upload a .docx file WITH text comment
  6. Verify the LHN shows the text content (not just [Attachment])
  7. After the message syncs, long press and verify "Edit comment" IS shown for attachment+text
  8. Repeat steps 2-7 with image, video, and PDF attachments to verify no regressions
  9. Go offline, upload an attachment (any type), verify edit option is NOT shown while optimistic
  • Verify that no errors appear in the JS console

Offline tests

  1. Go offline
  2. Upload a .docx file as attachment-only
  3. Verify the attachment renders with proper styling
  4. Verify edit option is NOT shown (optimistic attachment should not be editable)
  5. Go online, wait for sync
  6. Verify edit option is still NOT shown (attachment-only is never editable)

QA Steps

Same as Tests

  • Verify that no errors appear in the JS console

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
    • MacOS: Desktop
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I verified there are no new alerts related to the canBeMissing param for useOnyx
  • I followed proper code patterns (see Reviewing the code)
    • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I used JaimeGPT to get English > Spanish translation. I then posted it in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Fix isReportMessageAttachment to detect document attachment-only messages
where message.text is the filename rather than [Attachment]. Also strengthen
canEditReportAction to always block editing of attachment-only messages
regardless of optimistic status.

@MelvinBot message.text is not only the filename. Also contains link.
Example: Sample.docx https://staging.expensify.com/chat-attachments/8260136212361587477/w_5586f35116d3e3cbb98b95a51bfbac3bb921d804.docx

Good catch! Fixed — changed the strict equality check to startsWith so it correctly handles the "filename URL" format. Also added a test case with the real-world format you provided.

import type {Message} from '@src/types/onyx/ReportAction';

const attachmentRegex = new RegExp(` ${CONST.ATTACHMENT_SOURCE_ATTRIBUTE}="(.*)"`, 'i');
const originalFilenameRegex = new RegExp(` ${CONST.ATTACHMENT_ORIGINAL_FILENAME_ATTRIBUTE}="([^"]*)"`, 'i');

@MelvinBot it doesn't have data-name attribute.

Example html:

<a href=\"https://staging.expensify.com/chat-attachments/8260136212361587477/w_5586f35116d3e3cbb98b95a51bfbac3bb921d804.docx\" data-expensify-source=\"https://staging.expensify.com/chat-attachments/8260136212361587477/w_5586f35116d3e3cbb98b95a51bfbac3bb921d804.docx\" data-attachment-id=\"9180105352410595168\">Sample.docx</a>

You're right — completely rewrote the approach. Instead of relying on data-name, I now extract the filename from the anchor text and the source URL from data-expensify-source, then check if message.text is exactly "filename URL". This matches the real production HTML format you shared. Also updated all tests to use realistic HTML with data-attachment-id instead of data-name.

message.text contains the filename followed by the URL (e.g.,
"Sample.docx https://staging.expensify.com/..."), not just the filename.
Use startsWith to match correctly.

Real production HTML for document attachments uses data-attachment-id
instead of data-name. Extract filename from anchor text and source URL
from data-expensify-source, then check if message.text matches
"filename URL" exactly to distinguish attachment-only from
attachment+text messages.
