[Python] Adding Node to Python Firebase Function

I am trying to deploy a firebase function in python. In the main.py file I define a basic Flask server, this main.py imports fetch.py (another file -same directory- with my source code). The fetch.py file uses the python javascript package. I added javascript to requirements.txt too. This package needs Node.js installed in the environment. Is there any simple way I can add Node.js?

I saw these Docs but I feel like its not what I need because I am not calling any Node/JS code, rather Node just needs to be setup in the same environment. Calling this deploy command

gcloud functions deploy fetchPython \
--gen2 \
--runtime=python311 \
--region=us-central1 \
--entry-point=app \
--trigger-http \
--allow-unauthenticated


results in this

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Could not create or update Cloud Run service fetchpython, Container Healthcheck failed. Revision 'fetchpython-00003-muh' is not ready and cannot serve traffic. The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable within the allocated timeout. This can happen when the container port is misconfigured or if the timeout is too short. The health check timeout can be extended. Logs for this revision might contain more information.

running gcloud functions logs read fetchPython --region=us-central1 I get:
