The trackModified call in the tracking logic has a bug that incorrectly removes null from pathnames when it tries to remove hash or search values from the parsed path.

Currently:

let pathname = parsed.href.replace(parsed.hash, '').replace(parsed.search, '')

Where if parsed.hash or parsed.search are missing (which is mostly the case for FS files), the value is null
eg { hash: null, search: null}

  • In which case, we essentially trim null
    Converting /mypath/nulldir/file.js -> /mypath/dir/filejs and breaking builds (see JIT Build error  #4920) or potentially accessing the wrong files.

Fix checks if hash or search are set before replacing them

Fixes #4920
