I would check for three things:

1. Verify connection ARN. Make sure you are using the correctly formatted ARN and that it points to an existing and active connection. 
2. CHeck your IAM role used by cloudformation has the right permissions to access the codestar connection.
3. Are you using the correct service name/service prefix?

CodeConnection: Invalid Connection ARN arn:aws:codeconnections:us-east-1:930202xxxx:connection/xxxxxxe64-a2d4-43a7-XXXX-26xxxdf41c54d. Verify your input and try again.
