Spring-Boot OAuth2 Strange Behavior When Authenticating with Twitch-CodePudding

I have been trying to set up OAuth2 with Twitch through Spring for a few days now. I have resolved quite a few problems in that process but this one has stumped me. When I attempt to access one of the endpoints that I am trying to require users to be authenticated with Twitch for I am getting redirected to localhost:8080/login and being shown a page that simply reads "Login with OAuth 2.0" and has nothing else on it. My expectation was that Spring would automatically redirect me to Twitch's authentication portal and then Twitch would send me back to the Spring application after going through the OAuth process. Instead I am simply being shown that page and nothing is happening.

As far as what has been done so far to remedy this problem... pretty much nothing. I have not been able to find anyone else running into this problem so I am thinking that there are a few possible issues... Based on this tutorial

Thank you for your time and consideration, I appreciate the help.

Edit:

Something I have recently found that I thought might be prudent to add to this discussion - when I am attempting to access a secured page in my current setup I see this screen:

It looks as if the intended way Spring normally displays this screen is like this:

It's almost as if Spring simply is not seeing my Oauth provider. Not sure if this information is helpful but I thought I would include it. Springs intended behavior for Oauth is that when there is only one provider configured the /login page is skipped altogether. I would actually prefer this behavior to be exhibited (but given it sees no providers I presume it shows the page).

Try adding the .oauth2Client() in your configure method instead of .oauth2Login().

I was able to recreate the issue. You have specified:

spring.security.oauth2.client.registration.twitch.authorization-grant-type=AUTHORIZATION_CODE

While it should be:

spring.security.oauth2.client.registration.twitch.authorization-grant-type=authorization_code

Spring Boot is unable to load your configuration properties properly, so it's as if you have 0 client registrations configured.
