This needs to be documented somewhere but currently if you use CommonJS in your own app code it won't work unless you use require or .cjs, .cts etc

It will work if it's a dependency or node_modules

You can always import ESM though

Actually I got an issue from node_modules and then found this when I tried to debug it.

I updated my case, sorry for the trouble.
