Fusebox doesn't recognize property setting for sourceRoot

Question

I've inherited some javaScript/typeScript code I cant much change.

using:

• fuse v0.4.0
• fusebox v4.0.0,
• typescript 4.1.3
• I'm generating a bundle & sourceMap (bundle.js, bundle.js.map)

this sourceMap works, BUT ONLY if I do a text replace on the "sources" in bundle.js.map

• finding occurrences of : src/

  • {"version":3,"sources":["/src/lib/development.ts","/src/lib/server.ts"

• replacing with: ../../

  • {"version":3,"sources":["../../lib/development.ts","../../lib/server.ts"

Based on the docs, I should be able to set the sourceRoot property in fuse.js. but no matter what value i set, the output into bundle.js.map remains unaffected.

my folder tree looks like this:

my fuse.js looks like this:

task('default', async () => {
    const fuse = FuseBox.init({
        allowSyntheticDefaultImports: true,
        homeDir: '.',
        output: 'build/$name.js',
        target: 'universal',
        sourceMaps: { inline: false, sourceRoot: "" },
//        sourceMaps: { sourceRoot: "/src" }, 
//        sourceMaps: { sourceRoot: "/../.." },
//        sourceMaps: { sourceRoot: "test" },
