Nest: GraphQL auth guard custom decorator undefined

Created on 18 Mar 2020 · 3Comments · Source: nestjs/nest

Bug Report

I created a new nest 7 project and followed the authentication documentation, but for the graphql the decorator threw an error of undefined when using custom route decorator

Current behavior

GraphQL guard Custom decorator doesn't work.

Input Code

https://github.com/rained23/nestjs-graphql-decorator

Get JWT

curl -X POST http://localhost:3000/auth/login -d '{"username": "john", "password": "changeme"}' -H "Content-Type: application/json"

{
    whoAmI{
        username
    }
}

TypeError: undefined is not a function
    at exports.CurrentUser.common_1.createParamDecorator (/home/me/graphauth/dist/auth/user.decorator.js:4:53)
    at shared_utils_1.isFunction.args (/home/me/graphauth/node_modules/@nestjs/core/helpers/context-utils.js:32:28)
    at resolveParamValue (/home/me/graphauth/node_modules/@nestjs/core/helpers/external-context-creator.js:141:31)

Expected behavior

Should be working because it is from the official documentation

Thanks for reporting! Just fixed: https://docs.nestjs.com/techniques/authentication#graphql (update your decorator's code):

import { createParamDecorator, ExecutionContext } from '@nestjs/common';
import { GqlExecutionContext } from '@nestjs/graphql';

export const CurrentUser = createParamDecorator(
  (data: unknown, context: ExecutionContext) => {
    const ctx = GqlExecutionContext.create(context);
    return ctx.getContext().req.user;
  },
);
