Custom query params in redirect_uri for Bitbucket Server OAuth api v2 login

[a_marchenkov]

I'm building a web service which requires integration with Bitbucket Server, so I need to login and get a token.

So far everything works find until I add custom query parameter to the callback URL I defined when I created my Application Link. After it I got an error ``The provided value for the input parameter 'redirect_uri' is not valid.``

Is there a way that I can customize that URL on a per request basis? For example my default callback URL is /oauth/bitbucket, but I want to redirect to a different URL /oauth/bitbucket_login?sid={UUID}.
