Issue with AWS IRSA Configuration for Restore: S3 Object Header Forbidden (403)

[HamoucheTF1]

Report

When configuring AWS IAM Roles for Service Accounts (IRSA) for backups in the Percona MongoDB Operator, the backup process works correctly. However, restoring from the backup fails with a "Forbidden" error when trying to access S3 objects.

More about the problem

"error": "set resync backup list from the store: init storage: get S3 object header: Forbidden: Forbidden\n\tstatus code: 403"

Steps to reproduce

1. Configure AWS IRSA:
   Set up IAM roles and policies for the Percona MongoDB Operator.
   Annotate the Kubernetes service account with the IAM role ARN.
   refer to this doumentation: https://docs.percona.com/percona-backup-mongodb/manage/automate-s3-access.html#iam-roles-for-service-accounts-irsa
2. Configure Backup:
   Set up the Percona MongoDB helm chart to use IRSA for S3 backups.
   backups are created and listed successfully.
   backups are configured with psmdb-db helm chart

backup:
  enabled: true
  pitr:
    enabled: false
  storages:
    s3-us-west:
      type: s3
      s3:
        bucket: S3-BACKUP-BUCKET-NAME-HERE
        credentialsSecret: "" # empty and it works, the backup use the aws IRSA
        prefix: "someprefix"
        region: us-west-3

3. Initiate a restore process using the PerconaServerMongoDBRestore CRD.

apiVersion: psmdb.percona.com/v1
kind: PerconaServerMongoDBRestore
metadata:
  name: restore1
spec:
  clusterName: my-cluster-name
  backupName: backup1
  storageName: s3-us-west
 backupSource:
   type: logical
   storageName: s3-us-west
   destination: s3://S3-BACKUP-BUCKET-NAME-HERE/BACKUP-DESTINATION
   s3:
     credentialsSecret: "" # empty, i want to use the aws IRSA
     region: us-west-2
     bucket: S3-BACKUP-BUCKET-NAME-HERE
     prefix: "some prefix"
