Start with app/custom-oauth/server/custom_oauth_server.js, especially the getIdentity path at the reported line, then trace the request through packages/oauth2/oauth2_server.js. Reproduce login with the MiniOrange WordPress OAuth server and verify that the identity request succeeds with a non-empty access token.
