Adding the icon gives this error.

Still getting this same error. Fresh install with core 10.2.2. Should this have been solved on the duplicate issue?

Thanks @chucksimply - yes I think so. Then let's reopen this for further improvements. Can you see the root cause?

Looks like this is related to the S3FS module. In my settings.php, I have the below S3 settings...

$settings['s3fs.upload_as_private'] = TRUE;
$settings['s3fs.use_s3_for_public'] = TRUE;
$settings['s3fs.use_s3_for_private'] = TRUE;

But keeping these settings triggers the error noted in the original issue. If I comment these lines out, image uploads and manifest saves without issue. Sounds like this is directly related to the duplicate issue.

Should I create a new issue for this or include it in the related issue? Open to recommendations.

@chucksimply as this seems to be specific (possibly), you should please open a new issue for further investigation.
