Apache Superset oauth2 with custom Spring-Security OAuth2 server - spring

Question

I am using Apache Superset and trying to configure its OAuth2 capability to connect to my (custom) Spring-Security OAuth2 server. Unfortunately, it ain't working right now. The stack track begins with this.
15:09:16.584 [qtp1885996206-21] ERROR org.springframework.boot.web.support.ErrorPageFilter - Forwarding to error page from request [/oauth/authorize] due to exception [Could not resolve view with name 'forward:/oauth/confirm_access' in servlet with name 'dispatcherServlet'] javax.servlet.ServletException: Could not resolve view with name 'forward:/oauth/confirm_access' in servlet with name 'dispatcherServlet' at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1262) ~[spring-webmvc-4.3.8.RELEASE.jar:4.3.8.RELEASE] at
Here is the relevant portion of my config.py from Superset.
AUTH_TYPE = AUTH_OAUTH
OAUTH_PROVIDERS = [
{
"name" : "MY-OAUTH",
"icon" : APP_ICON,
"token_key" : "password",
"remote_app" : {
"consumer_key" : "my_dashboard",
"consumer_secret" : "my_secret",
"base_url" : "http://localhost:8088/myoauth",
"request_token_params" : {
"scope": "my_dashboard read write",
"grant_type" : "password"
},
"request_token_url" : None,
"access_token_url" : "http://localhost:8088/myoauth/oauth/token",
"access_token_params" : {
"scope": "my_dashboard read write",
"grant_type" : "password",
"response_type" : "authorization_code"
},
"access_token_method" : "POST",
"authorize_url" : "http://localhost:8088/myoauth/oauth/authorize"
}
}
]
A nice gentleman suggested that I have somehow disabled the servlet handler for /oauth/confirm_access, but I am not sure how to check on that or fix such a problem.
Do you know what is going on here, what I can do to fix this or where I can start looking?
Thanks,
Matt
