I have been noticing some strange behavior from one of my google cloud functions. It is a callable cloud function that is being called from my firebase app. Whenever I test the function it works as expected, but when I look in the logs I see a bunch of 204 status codes. I have a console.log statement as the first line, but whenever it ends with 204 status, that first line never executes. I am a bit confused as to why this is happening and would love some feedback!

Runtime is Nodejs 16.

Thanks

  • The Firebase SDK is automatically handling the required cors preflight request without invoking your code. Your function will execute on the followup request. – Doug Stevenson Feb 10 '23 at 00:07
