Thanks for the alert,

Let me loop somone in from the tech team to help validating this, and we will work it as a bug if we can.

Please share any further detail you can to reproduce, project id, data type etc.

@kaifish our engineering team is now tracking this error as part of investigation on an associated incident from last week.

For now if you can upload data manually or continue to work with existing buckets we will post a response, when we need more information from you or the issue is resolved.

Thanks again for reporting this and for your patience while we work to resolve this,

After reviewing your S3 configuration deeper it would seem that you are trying to use the ARN incorrectly for this S3 bucket:

Can you try reformatting your bucket to the following:

Hope this helps,

You might be seeing an old attempt to make it work, trying different options. I just tried again with the correct name, region, etc and it still is not working.
