Reproduction Example/SDK Setup

While reviewing the sentry/nextjs code in the search of a potential bug I stumbled upon this line of code:

sentry-javascript/packages/nextjs/src/config/withSentryConfig.ts

Line 435 in 468fc8c

['instrumentation-client.ts'],

For a quick overview:

  const potentialInstrumentationClientFileLocations = [
    ['src', 'instrumentation-client.ts'],
    ['src', 'instrumentation-client.js'],
    ['instrumentation-client.ts'],
    ['instrumentation-client.ts'], <-- This must be `.js`
  ];

Steps to Reproduce

See example

Expected Result

That instrumentation-client.js are also 'seen' by the sentry webpack code.

Actual Result

instrumentation-client.js is not scanned.
