How can I increase gunicorn --limit-request-line in a python App Engine application with Flask?

It is a sort question, I am building a very simple API with python runtime and Flask in Google Cloud Platform. Problem is that the request URL can get a bit long (approx 6000 bytes) and the current gunicorn limit is 4096. I know it will sound dumb, but I am trying to change it on the app.yaml file and when I run it it returns 500 server error. I am almost certain it is a problem in the entrypoint that I added because I do not know how to modify the app.yaml (I am new in web development). My app.yaml is as follows: 

runtime: python37
service: py
entrypoint: gunicorn --limit-request-line 8190 main:app

Could someone help me if you know what error I have? I have checked GCP documentation and demos but as usual they are not very descriptive.

You may need to have gunicorn in your requirements.txt if you don't have it already, as the docs mention.

Regarding the entrypoint in your app.yaml it looks correct, however I think you're missing adding the port to have App Engine listening to 8080, which is a requirement.

entrypoint: gunicorn -b :8080 --limit-request-line 8190 main:app

More information can be found as well in the following section of the documentation.
