Getting incorrect CORS 403 Error, resolves if I delete the Firebase function and re-deploy

Description

I deployed a Firebase Cloud Function which should not have been throwing a CORS error, since all my other cloud functions are called using the exact same code/headers/tokens etc and they are all working perfectly fine.

I get the following error message in the logs when I call this cloud function:

"The request was not authenticated. 
Either allow unauthenticated invocations or set the proper Authorization header. 
Read more at https://cloud.google.com/run/docs/securing/authenticating 
Additional troubleshooting documentation can be found at: 
https://cloud.google.com/run/docs/troubleshooting#unauthorized-client"

This error message is incorrect, it is not a CORS issue.

I deleted the failing cloud function and re-deployed, and now it works. I'm not sure what is going on, but obviously the error message being thrown is incorrect.

Hey @ahill187. Can you give me a code sample I can try to use to reproduce the issue? It can be one with minimal code, without any business / proprietary code. Thank you
