connexion and mangum

[AviranAbady]

I'm trying to deploy connexion using serverless AWS lambda using mangum, post requests with a body payload will fail due to BadRequestProblem("RequestBody is required")

The request body is stored in key "properties" and not in "default" making the validation code miss the body, any idea how to mitigate that?
mangum supports starlette ASGI but I cant get pass the validation.

/connexion/validators/abstract.py

# Handle missing bodies
headers = Headers(scope=scope)
if not int(headers.get("content-length", 0)):
    body = self._schema.get("default")
    if body is None and self._required:
        raise BadRequestProblem("RequestBody is required")
    # The default body is encoded as a `receive` channel to mimic an incoming body
    receive, scope = self._insert_body(receive, body=body, scope=scope)
