Custom Plugin with GraphQL Schema Queries

System Information
  • Strapi Version: 3.3.2
  • Operating System: Ubuntu
  • Database: Postgres
  • Node Version:
  • NPM Version:
  • Yarn Version:

I’m trying to create a custom plugin for a custom graphql schema.
Yes, i need to create a new custom query to access multiple strapi model services. I don’t need to extend an API Model.

I created the schema.graphql.js file under the plugin directory “config”:

module.exports = {
      definition: `
        type TestMe {
          username: String!
      query: `
        testMe: TestMe 
      resolver: {
        Query: {
          TestMe: {
            resolver: "",

But I get following error:

error Error: Field “Query.testMe” can only be defined once.

Any idea?
