Can't update existing function

[daniel sieradski]

TL;DR

It says in the directions:

This GitHub Action is declarative, meaning it will overwrite any values on an existing Cloud Function deployment. If you manually deployed a Cloud Function, you must specify all parameters in this action.

I take this to mean I can deploy to an existing function. However, I get an error when attempting to do so:

Failed to create function, function csp-reports already exists under Gen 2 environment. Please delete conflicting function first or deploy the function with a different name.

Expected behavior

To be able to overwrite an existing function

Observed behavior

Being forced to delete the existing function

Hi @selfagency

Did you create this function outside of GitHub Actions? It looks like this is a gen2 Cloud Function, and we do not currently support gen2 (#304). Cloud Functions gen2 is an entirely different API and set of fields.

Ah well that explains it then.
