@Gurram, Munisekhar Based on the error message, looks like the req_body is a string, likely because the JSON payload is double serialized.

You either must fix this in the client or add a check like this to make sure it is a dictionary

import json

def main(req: func.HttpRequest) -> func.HttpResponse:
    try:
        req_body = req.get_json()
        print(req_body)
        if isinstance(req_body, str):
            req_body = json.loads(req_body)
        project_id = req_body.get("project_id", None)
        print(project_id)
    except ValueError:
        filterdata = {}
    else:
        update_flag = req_body.get("update", 0)
        filterdata = req_body.get("filterdata", {})
