Proposal

I accidentally added the wrong S3 AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY and got a very unclear error when I tried to create a backup:

Please made an auth error more clear if possible. Something like 'Unauthorized access to s3' or 'Invalid creds'

Use-Case

Better debug is better

Is this a feature you are interested in implementing yourself?

@ksemele-public it will be improved under https://perconadev.atlassian.net/browse/K8SPS-469

@ksemele-public I’m happy to inform you that the MySQL Kubernetes Operator v1.0.0 was released today. This is the GA release, and you can start using it for production workloads. I also want to say a big thank you for using our operator and helping us improve it by providing feedback.
