My apologies for the delayed response; some unrelated work matters have taken my attention these last couple of days.
What should I have to share with you sir in order to get my problem solved?
Possible causes for "Unable to issue redirect for OAuth 2.0 transaction"? shows a great example of the code shared in order to help solve the problem. In a similar fashion, sharing your call to Auth0 would be great; thank you 
As I mentioned previously, just be sure to redact anything of a security or sensitive nature in whatever you share - like a secret or personal email - before posting
