harbor curated package unable to save ECR private registry is connection settings , gives internal server error

We are installing Harbor as EKSA curated package , i followed the guide and was able add public ECR registry. But when i try to add private ECR registry it gives internal server error and on the core pod logs i see an error saying
2023-08-08T09:35:43Z [ERROR] [/lib/http/error.go:56]: {"errors":[{"code":"UNKNOWN","message":"unknown: crypto/aes: invalid key size 10"}]}

The test connection works with access key and secret but its unable to save the connection.

Start with the Harbor core pod logs and the error reported at /lib/http/error.go:56, then trace how private ECR connection settings are validated and persisted. Reproduce the failure using the EKSA curated-package guide and compare it with the working public ECR connection. Done means a private ECR registry connection saves successfully without the internal server error.
