When using file loaders, processResult throws an error

[thatsmydoing]

When using an esbuild config with file loaders, the result.outputFiles may contain files other than the sourcemap and resulting js.

This causes an error here

karma-esbuild/src/bundle.ts

Lines 153 to 154 in bcf9982

	const map = JSON.parse(result.outputFiles[0].text) as RawSourceMap;
	const source = result.outputFiles[1];

when it tries to parse some other file as a sourcemap and fails

Do you have an example of how to reproduce this? I'm not sure what file loader you're referencing.

I meant this one https://esbuild.github.io/content-types/#external-file

So you could do

import url from "./somefile.txt";

and configure esbuild with

require('esbuild').buildSync({
  entryPoints: ['app.js'],
  bundle: true,
  loader: { '.txt': 'file' },
  outdir: 'out',
})

and it should output both the bundle and the .txt file into out
