TypeError: Cannot read property 'ids' of undefined, help needed

While I'm trying to mock Request form express I have following error message:

Test suite failed to run

    TypeError: Cannot read property 'ids' of undefined

Test which results in this error is below

import {Request} from 'express'
import each from 'jest-each'
import {createMock} from 'ts-auto-mock'

const notFoundError = (req: Request) => {
    throw new Error(req.method + ' ' + req.url + ' not found...')
}

describe('notFoundError', () => {
    each([
        ['GET', '/test/get/path', 'GET /test/get/path not found...'],
        ['POST', '/test/post/path', 'POST /test/post/path not found...'],
    ]).test('%s,%s', async (method, url, message) => {
        const mockRequest = createMock<Request>();
        mockRequest.method = method
        mockRequest.url = url
        try {
            notFoundError(mockRequest)
        } catch (e) {
            expect(e.toString()).toMatch(message)
        }
    })
})

I'm using "express": "^4.17.1",, "jest-ts-auto-mock": "^1.0.8", and "ts-auto-mock": "^1.4.3",. Any idea how to resolve it?

Hi, I'm sorry you are finding more issues. That ids error indicates that something got wrong when generating generics. I'll keep you updated :)

[bboguszewski]

No worries. It's the only way I can contribute ;)

Hi again, I had a quick look. Something is wrong with defaults generics. I've tried to default the generic doing this but there is another issue related to that generic.

createMock<Request<{ [key: string]: string; }>>();

You may have to wait few more days to use that interface

@barthpl morning and happy new year :) A new version has been released. 1.0.10 :) I've tested it with the entire express module. It should work, let me know if you have any issue. You may have to install the latest of ts-auto-mock if you've installed separately.

@uittorio happy new year to you too. Fix works perfect. Thank you.
If you decide to come to Wroclaw (Poland) let me know - I own you a bear.
