redwood: Errors on import while running jest

After upgrading to v0.34.0 I’ve found myself with all my tests failing on this kind of error:

 FAIL   api  api/src/services/products/products.test.ts
  ● Test suite failed to run

    Cannot find module '../../../../src/lib/db' from 'src/services/products/products.test.ts'

> 1 | import { db } from 'src/lib/db'
        | ^
      2 | import { disciplines } from 'src/services/disciplines/disciplines'
      3 | import { levels } from 'src/services/levels/levels'
      4 | import {

      at Resolver.resolveModule (../node_modules/jest-resolve/build/index.js:306:11)
      at Object.<anonymous> (src/services/products/products.test.ts:1:1)

The error in itself is that imports which use to work no longer work, eventhough files have not changed. This happens within tests files but also with imports that are in regular services. Thoses services work well with dev server started.

I’ve ran tests on a new project and it doesn’t seem to be related to v0.34.0 on new installs, but it could happen on upgrading projects.

Here are some relevant files:

// api/jest.config.js
module.exports = require('@redwoodjs/testing/config/jest/api')

// api/jsconfig.json

  "compilerOptions": {
    "noEmit": true,

    "moduleResolution": "node",
    "baseUrl": "./",
    "rootDirs": [
      "./src",
      "../.redwood/types/mirror/api/src"
    ],
    "paths": {
      "src/*": [
        "./src/*",
        "../.redwood/types/mirror/api/src/*"
      ],
      "types/*": [
        "./types/*"
      ]
    },
    "typeRoots": [
      "../node_modules/@types",
      "./node_modules/@types"
    ],
    "types": [
      "jest"
    ]
  },
  "include": [
    "src",
    "../.redwood/types/includes/all-*",
    "../.redwood/types/includes/api-*"
  ]
}

// api/tsconfig.json
{
  "compilerOptions": {
    "noEmit": true,
    "allowJs": true,
    "esModuleInterop": true,
    "target": "esnext",

    "moduleResolution": "node",
    "baseUrl": "./",
    "rootDirs": [

      "../.redwood/types/mirror/api/src"
    ],
    "paths": {

        "../.redwood/types/mirror/api/src/*"
      ],

      ]

    "types/*.d.ts"
  ]
}

// babel.config.js
module.exports = {
  presets: ['@redwoodjs/core/config/babel-preset'],
}

And finally, the test file:

import { db } from 'src/lib/db'
import { disciplines } from 'src/services/disciplines/disciplines'
import { levels } from 'src/services/levels/levels'
import {
  attributeDefaultMonitorToCourse,
  courseDefaultMonitor,
} from 'src/services/monitors/monitors'
import { productStub } from 'src/services/products/utilities'
import {
  createCourse,
  createProduct,
  product,
  products,
  updateProduct,
} from './products'

describe('products', () => {
  scenario('Retrieve a product', async (scenario) => {
    mockCurrentUser(scenario.user.manager)

    const p = await product({ id: scenario.product.one.id })

    expect(p.label).toMatch('Product label')

    expect(p.basePrice).toEqual(30)
  })

/** I'll spare you the other tests. */
