MismatchingRedirectURIError('(invalid_request) Mismatching redirect URI. <oauthlib.Request SANITIZED>

Hi all,
Can someone help me see where is the mistake on this call ?


It is returning

MismatchingRedirectURIError(’(invalid_request) Mismatching redirect URI. <oauthlib.Request SANITIZED>

I have also copied the link from this OAuth2 Mismatching redirect URI and changed the main address and client_id to mine and still the same error.

Wondering if the version of the OAuth (0.7.3) using on ERPNext V12 lib has anything to do!
