Hi,
when i run pbiviz start i now get the following error -
error LESS style/visual.less : The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined
to check that it is a common error i created a new visual that i did not edit and i still got this error.
has anyone come across it and know how to resolve the issue ?

Hi @tomdenby,
This isn't an error I've seen previously, particularly on a clean install/visual. I'd suggest creating an issue in the powerbi-visuals-tools repo so that the team can have a look. I'd recommend providing them the version of powerbi-visuals-tools you're using (run pbiviz --version) just in case it's useful to this particular case.
Regards,
Daniel
