Cannot use loader: { '.js': 'copy' }

[somebody1234]

I need it because the JS files are build outputs, not build inputs.
(esbuild is still used to transpile TS)
Go panics with interface conversion: graph.InputFileRepr is *graph.CopyRepr, not *graph.JSRepr on this line:

esbuild/internal/linker/linker.go

Line 1223 in e9413cc

otherRepr := otherFile.InputFile.Repr.(*graph.JSRepr)

Please provide a self-contained way to reproduce the issue.

upon further testing this is caused by https://www.npmjs.com/package/@esbuild-plugins/node-globals-polyfill. not sure what's the exact cause though...

found the issue. minimal repro:

touch a.ts; touch b.js; npx esbuild --outfile=c --loader:.js=copy a.ts --inject:b.js
