Marketplace : Unable to update OAuth Allow List

Our application is already listed / published in the Zoom Marketplace
Now we want to update our application to include another Endpoint in the OAuth Allow List.

There is an error showing up in the Web user interface for which we need your help:

I am editing our existing application form.

in the section “OAuth Allow List” I’m trying to add
https (colon, slash, slash) localhost:9876/someAuth
as a new entry

but when navigating to another field, I’m getting an error displayed at the top right:
“failed_to_update_oauth_client”

Can you kindly help to fix this issue???

If your app is already published, you have to add the new URL and submit the app for an update request. You can read more about them here: Updating an App - Distribute - Zoom Developer Docs

Why does the form throw an error with no further explanation?
and why is the field editable then?

Is your comment still valid when the ask is to keep the remaining endpoint unmodified and just add a secondary one?

I just tested edited the application in order for an update to be submitted. However, it does not allow me to add another Oauth endpoint.
A banner is alerting me that it will take 4+ weeks for the full submission process. Sorry, we really can not wait a month or more for adding one entry to the OAuth Allow Lists

Can you please provide guidance ?
