Firebase reset password link showed me error on the screen

Question

I tried both the custom action URL as well as the default URL *.firebaseapp.com/__/auth/handler, but no luck.

Both cases show the same error on the screen after clicking the link.

It says "The requested action is invalid."

Also I checked the console log, it says "Request is missing required data".

I also checked my GCP admin panel, and make sure there is no restriction to the browser key.

Where could possibly go wrong? Any help is appreciated ??

Answer 1

Sorry, I found the answer. I misused the action URL.

What I used previously was: https://mywebsite.com/__/auth/handler

Correct one should be: https://mywebsite.com/__/auth/action
