Compilation errors in nexus versions >= 0.11.5

[schuma7]

I'm using nexus together with apollo server and noticed that the following schema:

import path from 'path';
import { makeSchema, objectType } from 'nexus';

const Query = objectType({
  name: 'Query',
  definition(t) {
    t.string('_empty', {
      resolve: () => {
        return '';
      },
    });
  },
});

const schema = makeSchema({
  types: [Query],
  outputs: {
    schema: path.join(__dirname, '../schema.graphql'),
    typegen: path.join(__dirname, '../src/generated/typegen.ts'),
  },
});

export { schema };

produces these compilation errors:

node_modules/nexus/dist/builder.d.ts:203:6 - error TS2707: Generic type 'GraphQLObjectType<TSource, TContext>' requires between 0 and 2 type arguments.

203   ): GraphQLObjectType<

    ~~~~~
 21   >,
    ~~~

I've noticed the following:

• Running everything in dev mode using ts-node-dev --no-notify --transpileOnly --respawn src/server.tsworks without any issues (Using ts-node version 8.0.1, typescript version 3.2.4)
• Compilation works when downgrading to Nexus 0.11.4 while both 0.11.5 and 0.11.6 yield the errors shown above

I'm using Node v10.5.0 and my package dependencies are as follows:

Can you check your lockfile npm or yarn to see what version of @types/graphql is being pulled in - I'm guessing it's an older one than the one nexus was built with, as that's the only thing I see that might be causing the issue.

I believe the version you have does not specify GraphQLObjectType args as having a default, and the build .d.ts has:

export declare const isInterfaceField: (
  type: GraphQLObjectType<
    any,
    any,
    {
      [key: string]: any;
    }
  >,
  fieldName: string
) => boolean;

Anyway, adding "@types/graphql": "^14.0.7" to your devDependencies should fix it.

Changing to ^14.0.7 has indeed solved the issue, thank you very much for your swift response!
