working with 'The request is invalid' scenarios When Using Azure Function with Durable Functions in Python
I'm performance testing and I'm collaborating on a project where I've been banging my head against this for hours..... I'm trying to implement Durable Functions in Azure using Python, but I'm running into an scenario where I consistently receive a 'The request is invalid' behavior when triggering an orchestration function... My function seems to be set up correctly, and I followed the documentation for setting up Durable Functions in Python, but the behavior continues. Here’s the code for the orchestration function: ```python import logging import azure.functions as func from azure.durable_functions import DurableOrchestrationContext def main(context: DurableOrchestrationContext): logging.info('Starting orchestration...') result = yield context.call_activity('ActivityFunction', 'Hello, Durable Functions!') return result ``` I have also defined the activity function like this: ```python def main(name: str) -> str: logging.info(f'Running activity with input: {name}') return f'Activity completed with input: {name}' ``` When I trigger the orchestration using the HTTP start function, which looks like this: ```python import azure.functions as func from azure.durable_functions import DurableOrchestrationClient async def main(req: func.HttpRequest, starter: str) -> func.HttpResponse: client = DurableOrchestrationClient(starter) instance_id = await client.start_new('OrchestratorFunction', None, None) return client.create_check_status_response(req, instance_id) ``` I receive the behavior message: ``` The request is invalid. Please check the request payload. ``` I've verified that my function app is set to use the correct Python version (3.8) and have the `azure-functions` and `azure-functions-durable` packages installed in my requirements.txt. I’ve also made sure that the Azure Functions extension for Visual Studio Code is updated. I’m unsure if the scenario is related to the payload I’m sending or if there's a configuration scenario in Azure. Can anyone provide insight on what might be going wrong or how to debug this further? Any ideas what could be causing this? This is my first time working with Python stable. I'm coming from a different tech stack and learning Python. Has anyone dealt with something similar? I'm working on a REST API that needs to handle this. What are your experiences with this?
