Voyager fails to load (Unexpected reserved word at voyager:42:29: "await")

craigdrayton commented 3 weeks ago

I'm trying to use Voyager with a GraphQL Yoga server running Express:

import express from "express";
import { createSchema, createYoga } from "graphql-yoga";
import { express as voyagerMiddleware } from "graphql-voyager/middleware/index.js";
import typeDefs from "./generated/schema.json" assert { type: "json" };

const server = express();
server.use("/voyager", voyagerMiddleware({ endpointUrl: "/graphql" }));

const yoga = createYoga({ schema: createSchema({ typeDefs }) });
server.use(yoga.graphqlEndpoint, yoga);

server.listen(4000, () => {
  console.log("GraphQL Server is listening on http://localhost:4000/graphql");
});

When I try to access http://localhost:4000/voyager I get "Unexpected reserved word at voyager:42:29" error in console.

        displayOptions: undefined,

It's tripping up on the "await", which doesn't seem to be in an async function.

Downgrading to v1.3.0 resolves the issue

danieldanielecki commented 2 weeks ago

For me the error is different Cannot start Docker Compose application. Reason: exit status 1, and on v1.3.0 I'm having

ERROR in ./src/components/variables.css
Module build failed (from ./node_modules/postcss-variables-loader/lib/index.js):
BrowserslistError: Unknown browser query `dead`

This project doesn't seem to be maintainted anymore...
