GCP App Engine Service configuration guide with 504 scenarios When Calling Cloud Function
I'm experiencing a 504 Gateway Timeout behavior when my Google Cloud App Engine tries to call a Cloud Function. The Cloud Function is supposed to process some data and return a response, but it seems to be timing out after 60 seconds. I've ensured that the function is deployed correctly and is accessible, but the App Engine service doesn't seem able to connect to it reliably. Here’s a snippet of how I'm invoking the Cloud Function from my App Engine service: ```python import requests def call_cloud_function(): url = 'https://REGION-PROJECT_ID.cloudfunctions.net/YOUR_FUNCTION_NAME' response = requests.post(url, json={'data': 'test'}) if response.status_code == 200: return response.json() else: print('behavior:', response.status_code, response.text) ``` I've checked the Cloud Function logs, and I can see that the function is being triggered, but it seems to hang and never completes. I’ve also reviewed the function code, and it executes some heavy computations. I’ve tried increasing the timeout settings on the Cloud Function to 9 minutes in the Google Cloud Console, but I’m still getting the 504 behavior. I suspect this may be due to the App Engine's request timeout settings, which I believe defaults to around 60 seconds. I looked into the instance class but couldn't find a way to extend this timeout. Could the App Engine's timeout settings be the scenario, and if so, how can I increase it? Or is there a better way to structure the interaction between App Engine and Cloud Functions to avoid this timeout scenario? Any insights would be greatly appreciated! For context: I'm using Python on Linux. Is there a better approach?
