GraphQLError：语法错误：无法解析意外字符“。”

Question

I am currently using Apollo-server as my GraphQL server of choice and anytime I try to run tests I get the error indicated in the title. However, my server implementation works as expected.

 import 'cross-fetch/polyfill'; import ApolloClient, { gql } from 'apollo-boost'; const client = new ApolloClient({ uri: 'http://localhost:4000/', }); const USER = { invalidPassWord: { name: 'Gbolahan Olagunju', password: 'dafe', email: 'gbols@example.com' }, validCredentials: { name: 'Gbolahan Olagunju', password: 'dafeMania', email: 'gbols@example.com' }, usedEmail: { name: 'Gbolahan Olagunju', password: 'dafeMania', email: 'gbols@example.com' } }; describe('Tests the createUser Mutation', () => { test('should not signup a user with a password less than 8 characters', () => { const createUser = gql` mutation { createUser(data: USER.invalidPassWord){ token user { name password email id } } } ` client.mutate({ mutation: createUser }).then(res => console.log(res)); }) })

Answer 1

There is a problem with the document used in your test. USER.invalidPassWord is not valid GraphQL syntax. Presumably you meant to use a template literal there to reference the USER variable defined earlier.

Answer 2

Doing the GrapQL tutorial at

https://www.howtographql.com/react-apollo/1-getting-started/

gives the same error.

I have razed the "same" issue at their site, though is the problem another in my case.
