Functions in App Platform failing with " might just be timing out (default is 3000ms). (They should return HTTP 408 Request Timeout)

I’ve been battling with a (Python) Function deployed inside the App Platform, failing with a (pretty useless) “There was an error processing your request.” message.

Turns out that my function was just taking more than 3000ms to execute, which is the default timeout for a Function.

You can change the timeout in package.yml, by adding this to your Action:

actions: 
  - name: <your Function's name>
    limits:
      timeout: 30000 # The new timeout, in milliseconds

BUT, I think DigitalOcean should make any web Function that times out return an HTTP 408 Request Timeout, which would be more precise, and would give developers much more useful information to act upon (and save us a lot of frustration to debug).
