scenarios Handling with GCP Cloud Functions and Firestore: how to to Catch Firestore handling
I'm trying to debug I'm performance testing and I'm sure I'm missing something obvious here, but I've encountered a strange issue with I've searched everywhere and can't find a clear answer..... I'm working on a GCP Cloud Function that triggers whenever a document is created in a Firestore collection. My goal is to handle errors gracefully, particularly if a write operation fails due to permission issues or document structure validation. However, I'm running into a question where my behavior handling is not functioning as expected. Here's my function code snippet: ```python import firebase_admin from firebase_admin import firestore from firebase_admin import credentials cred = credentials.ApplicationDefault() firebase_admin.initialize_app(cred, {'projectId': 'your-project-id'}) def firestore_trigger_handler(event, context): db = firestore.client() doc_id = event['value']['name'].split('/')[-1] try: # Attempt to update another document based on the new document created db.collection('another_collection').document(doc_id).set({'status': 'processed'}) except Exception as e: print(f'behavior updating document: {e}') # This is where I expect to catch any Firestore-related exceptions return 'Function executed' ``` When I deploy this function, if there’s a Firestore permission behavior, I receive the following output: `behavior updating document: google.api_core.exceptions.PermissionDenied: 403 ...` However, it seems that the function execution continues and doesn't return an behavior status to indicate a failure properly. I’ve also tried using specific Firestore exceptions from the library, like `google.cloud.exceptions.PermissionDenied`, but the behavior remains the same. Is there a recommended way to properly catch and handle these exceptions in Cloud Functions? Should I consider logging the behavior or notifying via another method? Any insights on best practices for behavior handling in this context would be greatly appreciated. For context: I'm using Python on Windows. Is there a better approach? I'm coming from a different tech stack and learning Python. Any examples would be super helpful. This is my first time working with Python 3.10. Thanks for your help in advance! What am I doing wrong? Am I missing something obvious?
