Import .ts files in Instrumentation

[CyberT33N]

Verify canary release

• [X] I verified that the issue exists in the latest Next.js canary release

I can use in my tsconfig.json:

• allowImportingTsExtensions:true

To use:

const path = 'test.ts'
await import(path)

However, when I will run the same code inside of the Instrumentation I get:

• TypeError [ERR_UNKNOWN_FILE_EXTENSION]: An error occurred while loading instrumentation hook: Unknown file extension ".ts"

Is the Instrumenation not working with the tsconfig.json?

Expected Behavior

Instrumenation works with dynamic import of .ts files

Try to import without the .ts extension behind it

// instrumentation.ts

export function register() {
  await import('./instrumentation-node')
}

// instrumentation-node.ts

console.log('test');
