title: How can I increase gunicorn --limit-request-line in a python App Engine application with Flask?
body: <p>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: </p>
  
  <pre><code>runtime: python37
  service: py
  entrypoint: gunicorn --limit-request-line 8190 main:app
  
  </code></pre>
  
  <p>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.</p>
