Jest configuration in Angular 13: transform not working

Question

I'm encountering an issue with the Jest configuration in my Angular 13 project. The transform property doesn't seem to be working as expected, preventing Jest from transforming my TypeScript files during testing. Here are the details of my configuration:

Jest version: 28.x.x ts-jest version: 28.x.x Angular version: 13.x.x

In my jest.config.js file, I have the following configuration for the transform property:

transform: {
    '^.+\\.ts$': ['ts-jest', { tsconfig: 'tsconfig.spec.json' }],
}

However, when running Jest tests, I'm encountering the following error:

TypeError: configSet.processWithEsbuild is not a function

I've tried the following troubleshooting steps without success:

1. Updating Jest and ts-jest to their latest versions.

2. Clearing the Jest cache using jest --clearCache.

3. Verifying the compatibility between the versions of Jest and ts-jest.

4. Ensuring that my jest.config.js file is correctly configured with the necessary transform options.

I'm unsure what could be causing this issue. Any help or insights would be greatly appreciated. Thank you!
