Hi guys. We are trying to deploy a Lambda Docker image, but keep getting this error. Any ideas on how to fix?

{Error=TypeError, Cause={"errorMessage": "the 'package' argument is required to perform a relative import for '.app.lambdex_handler'", "errorType": "TypeError", "requestId": "", "stackTrace": ["  File \"/var/lang/lib/python3.9/importlib/__init__.py\", line 122, in import_module\n    raise TypeError(msg.format(name))\n"]}}
