Vertica 11 operator in Kubernetes

[commandLineCtrl._createDB_processResult] Error: Bootstrap on host 192.168.102.196 return code 1 stdout '' stderr 'Logged exception in writeBufferToFile: RecvFiles failed in closing file [s3://verticatest/verticadb_rw_access_test.txt]: Unable to connect to endpoint. Writing test data to file s3://verticatest/verticadb_rw_access_test.txt failed.\nTesting rw access to communal location s3://verticatest/ failed\n'

We use minio and we validate credential and endpoint are fine. In adminttools logs getting the above error. EON database is not getting created.

auth_params.conf
[dbadmin@verticadb-vdbsubcluster-0 ~]$ cat auth_parms.conf

awsauth = verticadb:xad91dsad
awsendpoint = minio.integration-shared.svc.cluster.local
awsenablehttps = 1
awsregion = us-east-1

We use the above creds only. region is setting by default not sure this is creating the issue.

Kindly let me know what needs to be validated.
