Backblaze B2: The XML you provided was not well-formed or did not validate against our published schema about minio-go

[m90]

It's probably relevant to note this error is returned from a method that calls ListObjects and RemoveObjects APIs.

Have you tested the tool with AWS S3 and MinIO ?

[m90]

S3 and MinIO still work as B2 previously did, yes (using these myself, not using B2 though).

[cbenard]

The tool creates tarballs and uploads them and prunes the older ones older than a threshold.

I don't have a way to repro with either of the ones listed. I don't have an account with AWS, nor would it have the accumulated files.

I don't have a way to run storage for MinIO currently which is why I am using offsite storage.

I don't know of a way to find out if B2 changed something, but I also cannot see the XML that @m90's tool is sending in the POST.

ListObjects doesn't send XML, so I'd guess the problem is with their implementation of RemoveObjects.

Since you say it happens "all of a sudden", my guess is it is a bug introduced by Backblaze. I suggest you reach out to them.

If you find more info and it is a bug on our side feel free to open a new issue - but if it works with AWS there isn't really more we can do here.
