Failed to create new s3 bucket with secretless broker for aws

Summary

I am trying secretless broker at my local to access aws s3 buckets, I can list the buckets fine, but I can’t create any new bucket. is this a bug?

I tried aws cli w/o secretless broker in between to create bucket, and it works fine. I am using the same account as above, and it is an admin.
