Can't access 'params' or 'auth' in Cloud Function triggered in Firestore
I asked this in the Firebase Google Group but think that's actually the wrong place so I'm reposting here. Hope that's OK.
The EventContext for Firebase Cloud Functions is pretty well described here. There it says that with an event triggered on a Firestore create at messages/{messageId}
I should be able to...
def process_message(event, context):
# What's in the context?
print(dir(context))
# Can I access 'messageId'?
print(context.params['messageId'])
No luck - context.params
doesn't exist, and dir(context)
returns ['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'event_id', 'event_type', 'resource', 'timestamp']
- definitely no params
in there.
The docs also suggest that context.auth
is available on Realtime Database triggers, but not Firestore? This is a shame as it would be really useful for securing functions.
Am I missing something here? Can anybody help me access context.auth
and/or context.params
in a Cloud Function written in Python and triggered by Firestore?
Thanks.

"The docs also suggest that context.auth is available on Realtime Database triggers, but not Firestore?" That is correct, thecontext.auth
value is only available for RTDB triggered functions. "This is a shame as it would be really useful for securing functions." Agreed, although commonly the user can be derived from the data they write. Feel free to file a feature request or add your vote to the existing feature request on github.
