TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for ...

[huan]

It's strange that the following error message appears from the GitHub Actions log yesterday.

I retried serval times but this error persists for a while.

However, it seems it's gone today, so I guess it's a bug related to GitHub Actions system.

> cross-env NODE_OPTIONS="--no-warnings --loader=ts-node/esm" tap "src/**/*.spec.ts" "tests/**/*.spec.ts"
