Additional details

Cypress with Typescript and ESM stopped working with node 22.7.0. Based on the node release notes the --experimental-detect-module flag is now enabled by default which doesn't play nicely with the experimental ts_node module loader that cypress is using under the hood.

Turning it off via --no-experimental-detect-module on the child process fixes the issue.

Steps to test

Unit tests added to have some coverage in the ProjectConfigIpc and a binary system test using node 22.7.0 has been added

How has the user experience changed?

I'm guessing that this issue might also occur if experimental-detect-module was explicitly enabled?

If so, then maybe mention this in the changelog.

It was introduced in Node.js 20.10.0. See https://nodejs.org/docs/latest-v20.x/api/cli.html#--experimental-detect-module.

  • Looking at your code, it seems you only do something different with Node.js >= 22.7.0, so the added comment is probably misplaced.

    Cypress uses its own loader for TypeScript and ES Modules to parse the Cypress config and likely will not work with the experimental-detect-module Node.js option.

  • I suggest reverting your addition to the changelog and dealing with ERR_INTERNAL_ASSERTION with Node.js >= v22.1.0 and experimental-detect-module set #30101 for Node.js < 22.7.0 separately. That would be cleaner I think.

I couldn't figure out another way to test this. Not great, but at least gets us what we need
