Common Issues

Overview

Here we outline some common problems you might face during development.

Incorrect Extension ID

Note that for Post-login PWA and local development, we use the gogonhoemckpdpadfnjnpgbjpbjnodgc extension ID, generated from the key attribute in package.json. For the Shimless RMA usecase, we use the jmalcmbicpnakfkncbgbcmlmgpfkhdca extension ID, generated from signing the extension.

Incorrect Chrome version

Only newer chrome version supports certain APIs. Verify you are on the newest Chrome version.

Incorrect file permission

Ensure that files can be viewed by the chronos user. Incorrect file permission may lead to errors such as:

• Not seeing the files in the file app
• CRX Header Invalid log

Incorrect allowlisted origins

You should make sure the the origins in these three places are equivalent:

1. externally_connectable attribute in the extension manifest
2. Actual URL of the PWA or IWA
3. Allowlisted URL in Chrome

For PWA, you should override 3. with the OS flag --telemetry-extension-pwa-origin-override-for-testing=$ORIGIN.

For IWA, the app built by running npm run build_iwa should automatically be the correct origin.
