serverless: Environment variables are not defined using SSM

I’m trying to use SSM to populate the environment variables, but for some reason it only works when I run the function locally. When the lambda runs on AWS, the process.env doesn’t have the added variables.

I’m following the docs: https://www.serverless.com/framework/docs/providers/aws/guide/variables/#reference-variables-using-the-ssm-parameter-store Also this blog post: https://www.serverless.com/blog/serverless-secrets-api-keys

@Lucasdsk you might want to update your serveless.yml with the latest update you have made; I believe you have also tried with - /my-path/my-path-env/* and it didn’t work either
