could not match param 'https://ift.tt/37uT19k' with whitelisted URL patterns in this Google project

I'm trying to whitelist [my-sub-domain.page.link/ChangePassword] URL Pattern to use this dynamic link to complete Firebase Password resetting.

And When I'm trying to debug this URL. it show this error:-

The dynamic link has 1 error(s)
We could not match param 'http://mydbtesting.page.link' with whitelisted URL patterns in this Google project.

I tried to use the examples that is mentioned in this link: https://support.google.com/firebase/answer/9021429 but the firebase dynamic link couldn't match it.

Can anyone give me a valid regex url pattern that can fix this problem?
