Source map generation error when deploying to Heroku

See original GitHub issue

I have been trying to add sass-brunch support to my app, which I deploy to Heroku. When I do so, I get a bunch of errors like the following:

error: Source map generation failed for 'tmp/build_bbbbbbbb/app/views/styles/foo.scss': ENOENT: no such file or directory, open '/tmp/build_bbbbbbbb/tmp/build_bbbbbbbb/app/views/styles/foo.scss'

I have tried both 3.0.0 and brunch/sass-brunch#master, both of which work locally for me (but I am on Windows), and both of which fail on Heroku. I am using node 14.17.0 and npm 7.14.0. Unsure if it matters, but my Heroku setup uses NODE_ENV=staging.

Any ideas would be appreciated. Thanks!

I was able to make a workaround fix for myself for this by change this line: https://github.com/brunch/sass-brunch/blob/master/index.js#L124

To be:

src.replace(process.platform === 'win32' ? 'file:///' : 'file://', '')
