Expected Behavior
When invoking a function which returns an "authorizer" like dictionary (has non-falsy "principalId" and "policyDocument" fields) using python3.7, the function should not return an error
Actual Behavior
A "Runtime.MarshalError" is returned because the python 3.7 lambda runtime cannot serialize bytes values (this feature was added in version 3.8)
Steps to Reproduce the Problem
Invoke a lambda function that returns {"principalId" :" ", "policyDocument": " "} using the python3.7 runtime.
You can also clone this serverless project that replicates the bug.
- Deploy setting the
DATADOG_API_KEY env variable to set a valid api key
- invoke the
failing function. It'll return an error.
A working function is also provided that workarounds the error by patching the lambda runtime code.
