Power BI Custom Visual - force directed graph API error

[vasher]

Hi,

I'm trying to create a custom Force Directed Graph using the source code on Github (PowerBI-visuals-ForceGraph) and following the tutorial available at creating-a-custom-visual. Unfortunately, when I try to start the custom visual using the "pbiviz start" command in PowershellI I get an error stating "Invalid API version v2.3.0".

The "circlecard" example project used in the tutorial, which also uses API version v2.3.0 in it's pbiviz.json file, works just fine. So I'm clueless as to what's causing this error. I'm very new to trying out custom visuals on Power BI so any help with this is greatly appreciated.

Thanks in advance!

1. $ git clone git@github.com:Microsoft/PowerBI-visuals-ForceGraph.git
2. $ cd PowerBI-visuals-ForceGraph
3. $ npm install
4. $ npm run pbiviz -- --create-cert
5. $ npm start

Let us know if it resolves the issue.

Thanks for the solution Ignat. I followed the steps but unfortunately step 3 produces the following errors:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents): 
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

Ignoring the errors/warnings and proceeding futher seems to work. However, for step 5, I had to use pbiviz start.

Thanks a ton for the solution!
