Random ModuleNotFound error

[joshuaavalon]

I am self hosting Windmill CE v1.373.1-1-g86e23f2ae.

When I updated and deployed a TypeScript (Bun) script, I often get the following error.

Bun v1.1.21 (Linux x64 baseline)

I cannot found a way to always reproduce it but I found adding //nobundling prevent it from happening.
Is there anyway to debug it?

Hi,

We pre-bundle the scripts at deploy time (unless //nobundling). Your issue should be reproducible locally using bun build <x> and then bun run on the output. You may want to raise an issue directly on the bun github project.
