CastError: Cast to [undefined] failed for value "["user"]" at path "roles"

[AdamBCo]

I am currently receiving the following error when running a Mongoose query in a test environment utilizing supertest and jest.

CastError: Cast to [undefined] failed for value "["user"]" at path "roles"

I am using Mongoose 5.6.9 with the code below:

The Query

const _id = req.params._id

User.findOne({
	_id,
	roles: 'admin'
})
	.exec()
	.then(user => {
		if (!user) {
			return next(boom.badRequest("No User"))
		}
		res.status(200).json(user)
	})
	.catch(err => next(boom.badRequest(err)))

The User Model

const mongoose = require('mongoose')

const Roles = ['user', 'admin', 'gallery', 'artist', 'appraiser', 'beta', 'super', 'contractor', 'auction_house']

const schema = mongoose.Schema(
    {
		name: {
			type: String,
			trim: true
		},
		roles: {
	        type: [{
	            type: String,
	            enum: Roles
	        }],
	        default: ['user']
	    }

    },
	{
		timestamps: {
			createdAt: 'created_at',
			updatedAt: 'updated_at'
		}
	}
)

module.exports = mongoose.model('User', schema)

Can someone please help me figure out what's going on?

Thank you

Maybe this is related to #8053

@esetnik Thanks for pointing me to that issue. Unfortunately it showcases the creation of a User object; whereas I am simply trying to find one. I'm not sure where the case issue is occurring.

The below script executes without error for me on 5.6.9, please modify the below script to demonstrate your issue.

const assert = require('assert');
const mongoose = require('mongoose');
mongoose.set('debug', true);

const GITHUB_ISSUE = `gh8058`;
const connectionString = `mongodb://localhost:27017/${ GITHUB_ISSUE }`;
const { Schema } = mongoose;

run().then(() => console.log('done')).catch(error => console.error(error.stack));

async function run() {
  await mongoose.connect(connectionString, { useNewUrlParser: true });
  await mongoose.connection.dropDatabase();
  
  const schema = mongoose.Schema(
    { 
      name: { 
        type: String,
        trim: true
      },
      roles: {
        type: [{
          type: String,
          enum: ['admin', 'super-admin']
        }],
        default: ['user']
      }
    });

  const User = mongoose.model('User', schema);

  await User.create({ name: 'test', roles: ['admin'] });
  const doc = await User.findOne({ roles: 'admin' });
  console.log(doc);
}

This looks to be a duplicate of #8053. It's a bug in Jest that we'll work around.

I strongly recommend moving off of Jest. Jest is an anti-pattern because it does so much monkeypatching that it creates a distinct JavaScript environment that isn't quite Node.js or a browser. Code that works in Jest may not work in Node.js and vice versa.

I had the same problem - I updated to 5.6.11 and it fixes it.
