Tutorial 6-authentication - singup:null, no error

[jeanatcismet]

I am following the tutorial and i just encountered a problem on the signup step:

There is no error (neither in the server console, nor in the API response). I don't know where the problem is.

The signup resolver is not beeing invoked (i have added a console.log('Test') on the top of the function to check this).

My package.json:

  "name": "hackernews-node",
  "version": "1.0.0",
  "main": "src/index.js",
  "license": "MIT",
  "dependencies": {

  }
