I have 16 workers subscribed to a topic and they are using pull mechanism to retrieve the messages from the queue.
I very frequently get Error: A pull requests for subscription '/subscriptions/quizizz-org/socket-worker' went to a server that is temporarily overloaded. Please try the request again.
as reply.
My first guess was that may be because of some quota limit, but I could not find any quota limit for pull requests send to a subscription.
