[Robert-Janagap]

let me see your schema.graphql

[Damilare1]

Please I am having similar challenges, has the issue been resolved. If it has, how was it resolved?

[AviIhej]

I am having the same issue.. has anyone figured it out?

[eveshi]

same issue as well, has the problem solved?

[chinadbo]

same

[Esom]

quite new to graphql but this error happens when this file "./src/schema.graphql" is empty ..a type must be created & also a mutation & resolver

[jackgray]

I am getting this error and it seems to have something to do with reading the token although I am using syntax defined in the prisma-auth example

here's the full output:

Debugger listening on ws://127.0.0.1:9229/b85422b9-0b37-4cee-a743-8bfc5882fccf

prisma generated just fine so I don't think it has anything to do with the schema or datamodel

utils.js file from the prisma-auth example:

const { verify } = require('jsonwebtoken');

class AuthError extends Error {
	constructor() {
		super('Not authorized');
	}
}

function getUserId(context) {
	const Authorization = context.request.get('Authorization');
	if (Authorization) {
		const token = Authorization.replace('Bearer ', '');
		const verifiedToken = verify(token, process.env.AUTH_SECRET);
	
	return verifiedToken && verifiedToken.userId;
	}
}

module.exports = {
	getUserId
};

and the index.js:

require('dotenv').config();

const { GraphQLServer } = require('graphql-yoga');
const { prisma } = require('./generated/prisma-client');
const { resolvers } = require('./resolvers');
const { permissions } = require('./permissions');
const { getUserId } = require('./utils');

const dev = process.env.NODE_ENV !== 'production';

const server = new GraphQLServer({
	typeDefs: 'src/schema.graphql',
	resolvers,
	middlewares: [ permissions ],
	context: (request) => {
		return {
			...request,
			prisma
		};
	}
});

// server.express.use(compression());
// server.express.use(helmet());
// server.express.use(cookieParser());

if (!dev) {
	server.express.set('trust proxy', 1);
}

const cors = {
	origin:
		dev ? process.env.CLIENT_DEV_URL :
		process.env.CLIENT_PROD_URL,
	credentials: true
};

// option object for graphql yoga
const port = 4000;
const options = {
	port,
	cors
};

server.start(options, ({ port }) =>
	console.log(`Server started, listening on port ${port} for [${process.env.NODE_ENV}]`)
);

[jackgray]

wondering how to get a more useful error output... vs code usually catches syntax errors in code so I don't think it's that

[Esom]

can i see the content of schema.graphql .. is it an empty file? if yes then it shouldn't be

[jackgray]

No, and I have also imported everything from my prisma-client. prisma generate would not run with an empty file. Prisma deploys just fine.

here it is:

# import * from "./generated/prisma-client/prisma-schema"

type Query {
	info: String!
	currentUser: User
	allUsers: [User!]
	feed(filter: String, skip: Int, first: Int, orderBy: CommentOrderByInput): Feed!
	filterComments(searchString: String): [Comment!]!
	comment(id: ID!): Comment!
}

type Mutation {
	updateUser(name: String, email: String, password: String, newPassword: String!): User!
	commentBill(billId: ID!, content: String): Comment!
	publishComment(id: ID!): Comment
	deleteComment(id: ID!): Comment
	publish(id: ID!): Comment
	signup(email: String!, password: String!, name: String): AuthPayload!
	login(email: String!, password: String!): AuthPayload!
	likeComment(commentId: ID!): Like!
	likeBill(billId: ID!): Like
}

type Subscription {
	newComment: Comment!
	newLike: Like!
}

type User {
	id: ID!
	email: String!
	name: String
	comments: [Comment]
	likes: [Like]
}

type AuthPayload {
	token: String!
	user: User!
}

type BillFeed {
	bills: [Bill]
	count: Int
}

type CommentFeed {
	comments: [Comment!]!
	count: Int!
}

[jackgray]

It seems to have something to do with parsing the token

[jblevins1991]

Any updates to this? I really need to get my graphql server up and running.

[tiagobnobrega]

Same here... that's strange. Maybe node version related. I worked around it by reading file contents and passing it to typedefs option, as if it was inlined in the code. Also I'm using ".graphqls" etension.

const typeDefs = fs.readFileSync('./src/schema.graphqls','utf8');
...
const server = new GraphQLServer({
  typeDefs,
  resolvers
});

I suspect it's failing to reconize the argument as as filepath for some reason, so it tries to parse the path as actual graphql schema.
Not why this happens though, I tried the same path for both fs.readFileSync and typeDefs option.
I also tried the full path, but no luck either.

[Shaderzero]

I managed to solve problem:

const server = new GraphQLServer({
  typeDefs: './src/graph.graphql',
  resolvers
})

And in file graph.graphql first line should be:

schema {
    query: Query
    mutation: Mutation
}

[AmrAbdalrahman]

same issue with me!
@Shaderzero try you code still not works.

[Shaderzero]

@AmrAlmagic
Problem is not in code for typeDefs: './src/graph.graphql'
for GraphQLServer important to have proper schema description in this file
my current index,js

import {GraphQLServer, PubSub} from "graphql-yoga";
import db from './db';
import Comment from './resolvers/comment';
import Mutation from './resolvers/mutation';
import Subscription from './resolvers/subscription';
import Post from './resolvers/post';
import Query from './resolvers/query';
import User from './resolvers/user';

const pubsub = new PubSub();

const server = new GraphQLServer({
  typeDefs: './src/schema.graphql',
  resolvers: {
    Comment,
    Mutation,
    Subscription,
    Post,
    Query,
    User
  },
  context: {
    db,
    pubsub
  }
});

server.start(() => {
  console.log('the server is up')
})

and schema.graphql

schema {
    query: Query
    mutation: Mutation
}

type Query {
    users(query: String): [User!]!
    posts(query: String): [Post!]!
    me: User!
    post: Post!
    comments: [Comment!]!
}

type Mutation {
    createUser(data: CreateUserInput!): User!
    deleteUser(id: ID!): User!
    updateUser(id: ID!, data: UpdateUserInput!): User!
    createPost(data: CreatePostInput!): Post!
    deletePost(id: ID!): Post!
    updatePost(id: ID!, data: UpdatePostInput!): Post!
    createComment(data: CreateCommentInput!): Comment!
    deleteComment(id: ID!): Comment!
    updateComment(id: ID!, data: UpdateCommentInput!): Comment!
}

type Subscription {
    comment(postId: ID!): CommentSubscriptionPayload!
    post: PostSubscriptionPayload!
}

input CreateUserInput {
    name: String!
    email: String!
    age: Int
}

input UpdateUserInput {
    name: String
    email: String
    age: Int
}

input CreatePostInput {
    title: String!
    body: String!
    published: Boolean!
    author: ID!
}

input UpdatePostInput {
    title: String
    body: String
    published: Boolean
}

input CreateCommentInput {
    text: String!
    author: ID!
    post: ID!
}

input UpdateCommentInput {
    text: String
}

type User {
    id: ID!
    name: String!
    email: String!
    age: Int,
    posts: [Post!]!
    comments: [Comment!]!
}

type Post {
    id: ID!
    title: String!
    body: String!
    published: Boolean!
    author: User!
    comments: [Comment!]!
}

type Comment {
    id: ID!
    text: String!
    author: User!
    post: Post!
}

enum MutationType {
    CREATED
    UPDATED
    DELETED
}

type PostSubscriptionPayload {
    mutation: MutationType!
    data: Post!
}

type CommentSubscriptionPayload {
    mutation: MutationType!
    data: Comment!
}

@tiagobnobrega
I tried your solution works with me however I also tried to upgrade node version still get the same error.
@Shaderzero
my code is here
please inform me if I make something wrong!

[AmrAbdalrahman]

I solved it !!.
My editor is webstorm and uses graphql plugin. it makes the extension for the schema with (graphqls) with change the extension to (graphql) works fine now.
@Shaderzero thanks for your attention.

Hey 👋, It seems like this issue has been inactive for some time. In need for maintaining clear overview of the issues concerning the latest version of graphql-yoga we'll close it.
Feel free to reopen it at any time if you believe we should futher discuss its content. 🙂

[walame]

Hello, new to GraphQL but was able to figure this out.

Basically, I had a javascript syntax comment on schema.graphql file:

// server/src/schema.graphql

type Query {
...

Once I removed the comment, the error was gone. I guess the // threw it off!

[nbhankes]

This solved a similar issue for me:

const server = new GraphQLServer({
  typeDefs: __dirname + "/schema.graphql",
  resolvers,
});

[Urigo]

Hey, @Urigo from The Guild here!

You might know us from projects such as graphql-code-generator, envelop or graphql-tools.

For a long time we thought that the Javascript ecosystem is still missing a lightweight cross-platform, but still highly customizable GraphQL Server.

In the past the awesome Prisma team took on that great challenge and now we are happy to announce that we are continuing them and just released GraphQL Yoga 2.0 - Build fast, extensible, and batteries-included (Subscriptions, Serverless, File uploads support) GraphQL APIs in Node.js 🚀

We have been working a long time on version 2.0 and have been using it in our clients projects for a few months now and shared a couple of alpha cycles here.
Thank you all for your feedback and suggestions, you made this release possible!

Please try Yoga out again, give us feedback and help us spread the word on the new release!
