Project Tooling
Expo with Firebase web js.
Detailed Problem Description
I am giving the model a prompt which is expected to generate a very long response. I have tried non-streaming and streaming mode and the failure occurs exactly after 3 minutes. Firebase transactions have 3 minute timeout but I am not using them. I have set the timeout to 20 minutes for the model.
In non-streaming mode the request failed with 502 error and in streaming mode I stop getting new Eventstream messages and a FirebaseError: AI: Failed to parse stream (AI/parse-failed).
Steps and code to reproduce issue

Hi @tejasvi, thanks for reporting this issue. This is caused by a default timeout of three minutes that we've set. This issue will be fixed after #8890 which should be going in soon.
