HTTP Triggering Cloud Function with Cloud Scheduler

Question

I have a problem with a job in the Cloud Scheduler for my cloud function. I created the job with next parameters:

Target: HTTP

URL

Thank you @Dinesh for pointing towards the request headers as a solution! For all those who still wander and are lost, the code in python 3.7.4:

import json

raw_request_data = request.data

# Luckily it's at least UTF-8 encoded...
string_request_data = raw_request_data.decode("utf-8")
request_json: dict = json.loads(string_request_data)

Totally agree, this is sub-par from a usability perspective. Having the testing utility pass a JSON and the cloud scheduler posting an "application/octet-stream" is incredibly irresponsibly designed. You should, however, create a request handler, if you want to invoke the function in a different way:

def request_handler(request):
    # This works if the request comes in from 
    # requests.post("cloud-function-etc", json={"key":"value"})
    # or if the Cloud Function test was used
    request_json = request.get_json()
    if request_json:
        return request_json

    # That's the hard way, i.e. Google Cloud Scheduler sending its JSON payload as octet-stream
    if not request_json and request.headers.get("Content-Type") == "application/octet-stream":
        raw_request_data = request.data
        string_request_data = raw_request_data.decode("utf-8")
        request_json: dict = json.loads(string_request_data)

    if request_json:
        return request_json

    # Error code is obviously up to you
    else:
        return "500"
