[keycloak-user] Getting abstract method error for creating external Provider SPI

[Haseb Ansari]

Hello,

     My usecase was with JWE tokens and hence I started with implementing
custom external IDP extension like oidc in keycloak. I started my SPI by
extending AbstractIdentityProviderFactory, AbstractOAuth2IdentityProvider,
OAuth2IdentityProviderConfig classes. But when I try to use this provider
for login I get the below error:


ERROR [io.undertow.request] (default task-15) UT005023: Exception handling

Can anyone help me where did I go wrong ?

Thanks
