Anyone to show me how to correctly setup

express-jwt

with

Express Apollo Server

? I can't figure out why jwt verification errors are not being thrown back to Apollo. I see

express-jwt

logging the error but never received in Apollo Studio Explorer. I am using it like this but I can't figure out how to blend it into the Apollo/GraphQL error handling loop. Should I apply it as schema middleware or just as a regular express request middleware?:

export function createContext(
  req: JWTRequest,
  prismaClient: PrismaClient
): GraphQLContext {
  return {
    req,
    prisma: prismaClient,
  };
}

async function startApolloServer(
  gqlSchema: GraphQLSchema,
  prismaClient: PrismaClient
) {
  dotenv.config();

  const app = express();
   // here is how I am using it but when token is invalid it prevents request from proceeding(which is okay) but the errors are not sent back to Apollo Studio Explorer like any other errors raised by resolvers.
  app.use(
    expressjwt({
      secret: process.env.JWT_SECRET!,
      algorithms: ["HS256"],
      credentialsRequired: false,
    })
  );

  // 1. Http Server
  const httpServer = http.createServer(app);

  // 2. Websocket Server
  const wsServer = new WebSocketServer({
    server: httpServer,
    path: "/",
  });

  const wsServerCleanup = useServer({ schema: gqlSchema }, wsServer);

  // 3. Apollo Server
  const server = new ApolloServer({
    schema,
    context: ({ req }) => {
      return createContext(req, prismaClient);
    },
    csrfPrevention: true,
    plugins: [
      // Proper shutdown for the HTTP server.
      ApolloServerPluginDrainHttpServer({ httpServer }),

      // Proper shutdown for the websocket server
      {
        async serverWillStart() {
          return {
            async drainServer() {
              await wsServerCleanup.dispose();
            },
          };
        },
      },
    ],
  });

  await server.start();
  server.applyMiddleware({
    app,
  });

  await new Promise<any>((resolve: any) =>
    httpServer.listen({ port: process.env.PORT }, resolve)
  );
  console.log(`🚀 Server ready at <http://localhost:4000>${server.graphqlPath}`);
