sourcemaps not working

[AlbertoElias]

Using the latest versions, sourcemaps have stopped working. I updated my karma config with no success.

I'm using these versions:

"karma": "^2.0.0",
"karma-rollup-preprocessor": "^5.0.0",
"rollup": "^0.54.0"

And this config:

rollupPreprocessor: {
	plugins: [...listOfPlugins],
	output: {
		sourcemap: 'inline'
	},
	format: 'iife',
	name: 'projectname'
}

Any suggestions?

Well, Rollup moved opts.sourcemap to opts.output.sourcemap in a recent release, but that was gently patched in 5.1.1. Still, it should work without the patch, you'll just get deprecation warnings.

I'm not sure what would cause source maps to stop being generated, but a simple repository demonstrating the issue would help.

Edit: I've just tested rollup@0.54 and karma-rollup-preprocessor@5.1.1 on a small project, and the source maps are being generated and coming through fine.

It's also worth nothing that both format and name have moved inside of output, so your config without deprecation warnings would look like this:

rollupPreprocessor: {
	plugins: [...listOfPlugins],
	output: {
		sourcemap: 'inline'
		name: 'projectname',
		format: 'iife'
	}
}

If you can put together a fresh repo that reproduces your issue, I'll attack the problem, otherwise I'm not sure what to suggest. Sorry @AlbertoElias!

Ok, I don't have the code up just yet, but will do in 1-2 weeks. Do you mind if we leave this issue open until then? Thanks a lot for your help!

That is fine, but please make sure the reproduction is a new repo, with only the code necessary to clearly reproduce the issue.

I have encountered this issue as well. So here is a repo that reproduces the issue:
