ALREADY_EXISTS error while trying to update function with dash instead of underscore in name

[vitorelourenco]

TL;DR

The error seems to be realated to how gcp treats function names. The correct function name was foo_bar but in the name field for the action, I had written foo-bar instead.

Expected behavior

An error message saying 'Failed to update' or a successful update.

Observed behavior

Error showing an attempt to create a cloud function with the "same name".

Does a Cloud Run service with that name already exist? You can check in the Google Cloud Console.

It does but it is the same service, it's a cloud function gen 2. In the clound functions console it's named as foo_bar (underscore) and in the cloud run console it's named as foo-bar (dash)

[sethvargo]

Does this happen every time? Or did you rename the function and then it started happening?

[vitorelourenco]

I've only started using github actions for it today, before that I would zip and redeploy via console. I do remember fiddling around with that function, back when I was moving it from GEN 1 to GEN 2. I may have changed it's name back then but I'm not sure if it was my doing or google's, since the function still displays with an underscore in the cloud functions console. It's also a pretty set-and-done function so it hasnt seen any new deployments for several months. I don't have other examples of this in our repo but that happens every time for this function. I was thinking this could be a problem related to the underlying tool instead of the action but the error I get is different when I use gcloud with the same arugments.

cloud run name: foo-bar
cloud function name: foo_bar

Are you able to put together a reproduction case from scratch? I'm having trouble reproducing this, so I must be missing a step.

[vitorelourenco]

I'll see if I can reproduce it over the weekend
