When trying to install a chrome extension using manifest_version 3, I am unable to install as I keep getting the error:
The "background.scripts" key cannot be used with manifest_version 3. Use the "background.service_worker" key instead
or
The "background.persistent" key cannot be used with manifest_version 3. Use the "background.service_worker" key instead.
Manifest V3 no longer supports background pages. Instead it now supports a new feature called service workers.
The key background in your manifest.json can no longer contain the field persistent, and also update the value from scripts to service_worker. Service worker cannot contain an array but can only contain a single string value.
Eg:
{
"name": "Test",
"description" : "Test Chrome Extension",
"version": "1.0",
"manifest_version": 3,
"background": {
"service_worker": "background.js"
}
}
