You have nice backtrace, so you can track it. E.g.

at org.keycloak.broker.oidc.OIDCIdentityProvider.verifyAccessToken(OIDCIdentityProvider.java:515)

keycloak/keycloak/blob/12.0.2/services/src/main/java/org/keycloak/broker/oidc/OIDCIdentityProvider.java#L515


      
                  }
                  throw new IdentityBrokerException("Failed to invoke url [" + url + "]: " + msg);
              }
              return  response;
          }
          
          private String verifyAccessToken(AccessTokenResponse tokenResponse) {
              String accessToken = tokenResponse.getToken();
          
              if (accessToken == null) {
                  throw new IdentityBrokerException("No access_token from server.");
              }
              return accessToken;
          }
          
          protected boolean verify(JWSInput jws) {
              if (!getConfig().isValidateSignature()) return true;
          
              try {
                  PublicKey publicKey = PublicKeyStorageManager.getIdentityProviderPublicKey(session, session.getContext().getRealm(), getConfig(), jws);

So accessToken is null and backtrack it back to find more details.
