Incorrect error message "Invalid redirect url" during OAuth authorization

Description/Error
We have a fully working integration that is successfully creating meetings on behalf of our users so we are confident that the configuration (including the redirect_url) is all set up correctly. However, if a user enters the incorrect credentials when logging into the Zoom sign-in page (https://zoom.us/oauth/signin) then the user is re-directed to a page with an error message that reads “Invalid redirect url (4, 700)”.

Which Endpoint/s?
https://zoom.us/oauth/authorize

How To Reproduce (If applicable)
Steps to reproduce the behavior:

  1. Load the URL https://zoom.us/oauth/authorize?response_type=code&client_id={clientId}&redirect_uri={redirectURL} without being logged into a zoom account.
  2. Redirected to the login page https://zoom.us/oauth/signin?_rnd={randomNum}&client_id={clientId}&redirect_uri={redirectURL}&response_type=code
  3. Type in a valid Zoom account with an incorrect password
  4. Redirected to a page with an error message reading “Invalid redirect url (4,700)” rather than any indication of entering incorrect credenials

Screenshots (If applicable)

Additional context
As stated previously, this works properly if the correct credentials are entered so we know that the redirect URL is correct.
