Cannot fetch parameter from ssm parameter store in local tests

Type: Bug

aws-parameter-store-config

Describe the bug

Hi everyone, I'm having an issue with aws-parameter-store-config only locally (everything works on aws) so I guess I have a problem within my local setup.

I'm trying to use localstack to mock SSM in my integration test. The application can connect to the store (I debugged and see this request is successfull) but it's returning empty result.

Sample
I've created a sample app here and the steps to reproduce are in the readme file.

Do you have any ideas?

Thank you in advance!
