[Bug]: Github actions repoter throwing error

[param-finder]

Version

^26.6.3

Steps to reproduce

Add reporters: ['default', 'github-actions'], in the jest.config file and run the tests.

Expected behavior

It should pass the test command

Actual behavior

$ jest
Error: Could not resolve a module for a custom reporter.

error Command failed with exit code 1.

Additional context

I'm following the jest docs and its mentioned there as, I assume there's no need to install explicitly a custom reporter for this. If so, what's the official package name?

GitHub Actions Reporter
If included in the list, the built-in GitHub Actions Reporter will annotate changed files with test failure messages:

{
"reporters": ["default", "github-actions"]
}

Environment

GitHub Actions Reporter only works with Jest 28.

By the way, config documentation for Jest 26 can be found here: https://jestjs.io/docs/26.x/configuration

@mrazauskas I updated to v28 and now I'm getting facebook/react-native#33751 (comment)

● Invalid return value:
      `process()` or/and `processAsync()` method of code transformer found at
      "/Users/.../assetFileTransformer.js"
      should return an object or a Promise resolving to an object. The object
      must have `code` property with a string of processed code.
      This error may be caused by a breaking change in Jest 28:

[mrazauskas]

Your transformer which is mentioned in the error message is causing this. Just follow upgrade guide. The link to the guide is also included in the error message (;

shows

I get the error but would be better if there are any resolution steps for solving this error with respect to react-native. The assetFileTransformer.js happens to be inside react-native/jest which is beyond our control. As I've checked react-native package.json is still using version 26.6.3
