Backup not working with Service accounts using Web identity Tokens

I have noticed that the backup functionality does not work when I use a service account with web identity token. I get the error message below.

ERROR (OverseerThreadFactory-54-thread-3) [c:Collection s: r: x: t:] o.a.s.c.a.c.CollectionHandlingUtils Collection Collection, operation backup failed => org.apache.solr.s3.S3Exception: An AmazonServiceException was thrown! [serviceName=S3] [awsRequestId=56HQCK517V8WD2EE] [httpStatus=403] [s3ErrorCode=null] [message=null]
I also get a 400 error on some occassions.

I am currently running on solr version 9.8.1 and solr operator v0.8.1

I saw a similar thread on https://github.com/apache/solr-operator/issues/475 and apparently it has been resolved on versions 8.11 and higher.

Is there any part of the back up process I may be missing when working with Web Identity token?

Start by reviewing the backup configuration for Kubernetes service accounts with web identity tokens in Solr 9.8.1 and solr-operator v0.8.1. Compare the behavior and resolution described in solr-operator issue 475, then reproduce the backup against S3 while checking the reported 403 and 400 errors. Done means backups succeed with this authentication setup.
