Dreamweaver - SCSS/LESS compile issue.

Hello,

From past few days I'm unable to compile SCSS/LESS.
I've followed compile process from Dreamweaver with below steps:

I've setup for compile process with set default setting as per below mention.

1) Configure Dreamweaver into manage Site.

2) Set CSS Preferences > General > Deselect - Auto Compile

3) Set Source & Output > Define Output folder & Source folder with appropriate data path.

4) After all setting process.

5) open SCSS file and update it and compile it from Tool > Compile path

6) After completed that process by followed that process, My whole HTML structure looks destroyed.

It's shows below error in my compiled file:

/*

Error: Undefined variable: "$helvetica".

        on line 2 of C:/Program Files/Adobe/Adobe Dreamweaver CC 2019/configuration/SassFrameworks/base/_variables.scss

        from line 3 of C:/Users/krunal/Desktop/test/scss/vendors/bourbon/bourbon/settings/_settings.scss

        from line 10 of C:/Users/krunal/Desktop/test/scss/vendors/bourbon/_bourbon.scss
