source map generated by rollup miss 'file' property

[ash0080]

I do not know if it's a bug, because it's too trivial...
The source map generated by rollup miss 'file' property like this

{"version":3,"file":null,"sources":["..

but, without the file name, WebStorm will ignore the source map, so you can't debug in it.
thought it's easy to be fixed manually, but with --watch, means very annoying.

rollup version 0.36.0 with rollup-plugin-typescript

I'm running into a similar problem in the chrome debug extension for vscode which complains about not finding the correct file names.

EDIT: Curiously, the spec clearly states that the file property is optional

[ash0080]

@marvinhagemeister Yes, file property is optional, so you can debug it in Chrome, but seems the IDEs need the anchor to map the right files in source

I can't reproduce this, is it still happening with the current version? If so, please include a repro – thanks

This only happens when using plugins.
