AWS System Manager Backend support for MWAA

Question

I've tried to configure my MWAA (wih 1.10.12, 2.0.2) with ssm backend with below configuration options:

```
secrets.backend: airflow.providers.amazon.aws.secrets.systems_manager.SystemsManagerParameterStoreBackend
secrets.backend_kwargs: {"connections_prefix":, "variables_prefix":""}
```
It starts up the environment and status becomes 'Available' for use, yet while accessing the airflow UI, I'm getting  gateway errors.
I've also added permission for SSM.

Am I missing something or there is a known bug which I'm unaware of?

Answer

Yes, it is a known MWAA behaviour as per MWAA documentation "https://docs.aws.amazon.com/mwaa/latest/userguide/connections-secrets-manager.html"  AWS SSM Parameter Store is not a supported backend at this time on Amazon MWAA.

However, could you please follow below documentation if you would like to get the secrets manager config working in your MWAA environment.
