Error while trying to compile src (I am using basic HTML version)

Here are the steps I did:
1. I renamed folder src to metronic-src and tools to metronic-tools (to not mix it with my project). Also I moved them into my project.
2. I made necessary changes to gulp.config.json

{
 "config": {
 "path": {
 "src": "../metronic-src"
 },
 "dist": [
 "../dist/metronic-assets"
 ]
 }
}

Error in plugin "sass"
Message:
..\metronic-src\sass\components\components.scss
Error: join(null, "..\..\..\..\tools\node_modules\bootstrap\scss\bootstrap"): part 0 was null, but part 1 was not.

Some hints:
- gulp command works without metronic-src folder
- gulp command works in demo folder

I think this is issue with scss paths since I removed 1 folder nesting from gulp.config.json, this should be configurable, but the config I have is different from config from documentation so I am confused there, original config looks like this:

{
"config": {
"path": {
"src": "../{demo}/src"
},
"dist": [
"../{demo}/dist/assets"
]
}
}
