I tried to upload a new version of my addon which includes an Embedded WebExtension for migrating the storage.
I got following error:
Your add-on failed validation with 1 error.
The add-on ID in your manifest.json or install.rdf (...) does not match the ID of your add-on on AMO
But here they say the Embedded-extension will be ignored if having an addon-id set.
So: Do I need to set the id inside package.json or not?
