Hi

I am new to custom visual development, and trying to build my first custom visual. I am following the below link
https://learn.microsoft.com/en-us/power-bi/developer/visuals/custom-visual-develop-tutorial-format-o...

In the step "Adding custom formatting options", when I try to replace the code in Settings.ts I get the below error.

Please advice on how to fix the error. 

The version of powerbi-visuals-tools is 4.0.5
