File not found exception when requesting token

I am using the google app auth example. I modified the urls as per my oauth provider. I have specified the a valid authorization endpoint, client id, redirect uri, token uri, scope(openid, profile, email), response type (Code). I don’t know if there is a way to add consumer secret. I have not seen anywhere in the sample code a way to add consumer secret. When I run the app, I see our sso page, I am able to login, redirect happens. When the request to get token gets executed, I get an exception. The token request is failing. Any idea why this would happen? The token exchange url is correct and I am not sure why it is complaining about file not being found at that particular token url. Any pointers on digging more into this issue?

Im getting the same error but I’m using my own keycloak server. I get the SSO login screen but when it does the callback I get:

I check the Auth and Token URI and they are correct and on the keycloak server I see I have active session with my login.

@Johnnie843 were you able to resolve this issue? I’m also getting the same error with my Keycloak server.
