Attribute Slicer

Hi Team,

We are trying to reuse your code to build a similar search custom visual with additional functionalities, while trying use your code, we are facing issues with installation of a dependent module, viz. "@essex/attribute-slicer": "^2.0.1". It says "ERR! 404 Not found" when trying to install it through "npm install" command from the directory where the package.json is present. And same happens with Yarn as well. While trying to strat the visual using pbiviz start, it says Invalid API Version v1.8.0

Could you please help overcome the above. 

Thanks in advance,

VJ
