Uploading images in the Site Editor results in "Invalid parameters: post" on Simple and Atomic sites

[filipanoscampos]

Quick summary

When trying to upload images in the Site Editor, an "invalid parameter(s)" error message appears, and the image fails to upload. This issue appears to be specific to the Site Editor; uploading images still works fine in the post/page editor and the Media Library. I've tested this with various Full Site Editing (FSE) themes, and the error persists regardless of the theme used.

Steps to reproduce

1. Load the Site Editor (Appearance > Editor)
2. Add an Image or Media & Text block (or any other block that allows for image uploads)
3. Try to upload an image file

The issue can also be replicated if you add a Block pattern and try to replace the images included by uploading your own.

What you expected to happen

The image is correctly uploaded and displayed.

What actually happened

This failed and we see the message "Invalid parameters: post".

Uploading the image to the Media library first and then using the "Select Image" option to select it from the Media library worked for this site.

I constantly run into this issue when building sites for customers (BBE). Although it's not a complete blocker, it's pretty annoying and does waste time.

I shared the workaround of uploading to the media library first

Reproduced with the Ritratto theme. (The Hemingway one.)

• Activate the theme
• Click on the big image of Hemingway
• Click replace
• Click upload
• Select an image
• Get the invalid results notification
• Then see a missing image like the screenshot below

Reproduced this issue with TT4 on an Atomic site. Downgrading Gutenberg to 17.0.3 no longer reproduces the issue, while 17.1.0 still has this problem.

Temporary workaround is to open media library and upload image from there

Another report in 7450454-zd-a8c (Atomic, Creatio 2 theme).

Of note: only the Home (Blog Home) template appears to be affected. Trying to upload an image from your device results in the Invalid paramter(s): post error, while trying to upload an image from Pexels or Openverse results in a similar Invalid paramter(s): post_id error. Replicated this on a test site using TT3 as well.
