Cannot get simple GraphQL call to complete after following tutorial

[GQAdonis]

Steps to reproduce

I hope this is the place to ask this question, but I followed the instructions in your tutorial for feathers-plus to the letter. I am using a MongoDB instance, configured authentication (that works), with ONLY Users and Roles services in the simplest possible configuration.

I ran all the appropriate generation scripts at the appropriate times.

Expected behavior

What I expected was to be able to run this simple query from within GraphIQL:

{ getRole(key:"5c4f198068b713cd0c08b2b9") { name } }

and receive the appropriate response (after inserting roles into my MongoDB database).

Actual behavior

Instead, I get the following error:

Also ensure that there are not multiple versions of GraphQL installed in your node_modules directory. at new BadRequest (/Users/gqadonis/Projects/TribeHealth/sprint1/air-server/node_modules/@feathers-plus/graphql/node_modules/@feathersjs/errors/lib/index.js:81:17) at graphql.catch.err (/Users/gqadonis/Projects/TribeHealth/sprint1/air-server/node_modules/@feathers-plus/graphql/lib/index.js:79:17) at process._tickCallback (internal/process/next_tick.js:68:7) error: BadRequest: Schema must be an instance of GraphQLSchema.

System configuration

I am on a MacBook Pro using Node.js version 10.15.

Module versions (especially the part that's not working):

NodeJS version:

Operating System:

Browser Version:

React Native Version:

Module Loader:

Some extra information:

The code in the repo for this article (https://medium.com/@mattchewone/graphql-with-feathersjs-4cc67e785bd) works. However, when I update it using "feathers-plus generate all", that code stops working.

Something seems broken in the current release of the feathers-plus cli....

What are the contents of src/services/graphql/graphql.schema.?s of your project?

[GQAdonis]

Thanks @eddyystop! Here are the contents of the graphql.schema.js file:

// Define the combined GraphQL schema. (Can be re-generated.)
// !code: imports // !end
// !code: init // !end

let moduleExports = `
type Role {
  id: ID
  name: String!
}

type User {
  id: ID
  email: String!
  firstName: String!
  lastName: String!
  password: String
  roleId: ID!
}

type Query {
  getRole(key: JSON, query: JSON, params: JSON): Role
  findRole(query: JSON, params: JSON): [Role]!
  getUser(key: JSON, query: JSON, params: JSON): User
  findUser(query: JSON, params: JSON): [User]!
}
`;

// !code: exports // !end
module.exports = moduleExports;

// !code: funcs // !end
// !code: end // !end

The schema looks fine. How exactly did you make the GraphQL call? I mean was it via REST or WebSockets and what was the code making the call?

[eddyystop]

The format for calling the graphql service within Feathers is graphql.find({ query: { query: '{ getRole(...) {...} }' } }).

Don't forget to include the second query in a REST call.

[GQAdonis]

Thanks again for your quick response. I am not using feathers-client to make the GraphQL call. I was using GraphIQL (the graphical Mac app) for testing. I also used CURL manually with both GET and POST requests.

As I said earlier the code base for the sample article at https://github.com/Mattchewone/feathers-graphql-demo works, but it was generated with an older version of the CLI. When upgrading this code base to the current libraries using generate all, it stops working.

Make sense?

[eddyystop]

Others are making GraphQL calls without issues, so let not sidetrack ourselves with Matt's repo.

I have no experience with the Mac graphql app, so I don't know if it automatically inserts a query in front of the query string you are using, like Graphiql does. Please try a string without the shorthand syntax.
