Custom Visual Setup Exceptions (pbi-visuals-api 2.2.2, pbi-visuals-utils-dataviewutils 1.5.0)

Ok, I answered my own question: for all those risk takers out there willing to take a deep dive into powerbi-visuals-tools 3.0, but have an older version installed pay close attention to this article: https://microsoft.github.io/PowerBI-visuals/docs/how-to-guide/migrating-to-powerbi-visuals-tools-3-0/ with special emphasis on the section titled: "How to install powerbi-visuals-tools@beta"

What this article fails to mention is that if you have an existing version of the tools installed globally on npm, instead of simply running the command:

npm install powerbi-visuals-tools@beta

You must update your global instance as well with: 

npm install powerbi-visuals-tools@beta -g

Make sure you includ the global flag "-g" to update your local toolset. Then, create a new visual like so:

pbiviz new {name}

and run it with the following command: 

npm run start

and you will see the new webpack runner in the command window.

**note: I had to update my security certificate as well with:

pbiviz --install-cert

follow the prompts after you run this command and you should be good to go. Hopefully this helps someone :)
