Failed to read file with esbuild sourcemap option enabled

[nicolas-brousse]

I just switch from postcss standalone usage to this esbuild plugin.

I've got a error while building assets when esbuild sourcemap option is activated. Not really sure what is the exact issue.

I did a small add to reproduce my issue https://github.com/nicolas-brousse/esbuild-plugin-postcss2-sourcemap-example

% yarn build:js                                                                                     
yarn run v1.22.10
$ node esbuild.config.js
