Hi there,

I’m working on using Discourse as SSO, however whenever I make the call to “/session/sso\_provider” I get an error. The log shows the following:  
NoMethodError (undefined method `match' for nil:NilClass) /var/www/discourse/app/services/wildcard_domain_checker.rb:7:in `check\_domain’

I’m using build v2.3.0.beta8 +44

Is this a known issue?

Thanks,  
Iscle

Thanks.

What is the value of `sso provider secrets` in your site? We changed how the setting work, and now it’s a list of (URL, secret) tuples. Sounds like you have a tuple where the URL is missing?

Hi Rafael,

Thanks for your answer, I just solved the issue!  
It turns out I was missing “https://” on the return url (in the backend of my app)! Very stupid mistake, I know… Maybe you can add a check to avoid that from happening?

Anyway, thanks again 😃  
Have a nice day!
