Description

I'm building with TS and esbuild.

Using v7.5.2

This is used as a side effect of @opentelemetry/auto-instrumentations-node

It seems like __require.cache doesn't exist?His is bundled with esbuild for node 22

Research direction

Start at ExportsCache.has and Module.patchedRequire, the entry points shown in the stack trace, and inspect how __require.cache is accessed when the package is bundled with esbuild. Reproduce the failure with Node 22 and a TypeScript build; done means the require hook no longer throws when __require.cache is unavailable.
