Hello,
I need help to this error : Unable to issue redirect for OAuth 2.0 transaction.
We have this error after passing the connexion page of the enterprise.
"error": {
"message": "Unable to issue redirect for OAuth 2.0 transaction",
"oauthError": "server_error",
"type": "oauth-authorization"
},
In addition, for normal connexion with google, users in Auth0, … it always pass.
Here is the link that we followed : Connect Your App to ADFS
Thanks for the answer 
Hey @jydhenain , Welcome to the Auth0 Community.
Have you double-checked your redirect URL? This type of error can come if the redirect URL is not valid.

Sid
Thank you @sidharth.chaudhary, problem resolved 
Can you share for the benefit of others what it was?
Of course @konrad.sopala,
In the URL redirection, I use redirectUrl (redirectURL) as paramater’s name instead of redirectUri,
So, I changed redirectUrl to redirectUri and that solved the problem.
Perfect! Thanks for sharing that with the rest of community!
