However it doesn't work

Hi @Husain,

Did you follow the instructions in the repo about installing the correct version of powerbi-visuals-tools? From the error message in your screenshot, I would assume that you're attempting this on 3.1 or higher?

If so, you will need to install version 2.5 as per the linked instructions:

npm install -g powerbi-visuals-tools@2.5.0

Note that you will need to re-generate your certificate as this is matched to the version of the tools that you have installed. In versions prior to 3.1, this process is a 2-step process:

pbiviz --create-cert
pbiviz --install-cert

Good luck!

Daniel

Hi @dm-p 

I tried these steps. I get following error now

HI @dm-p 

When I downgrade and install cert

npm install -g powerbi-visuals-tools@2.5.0

My other custom visuals stop working and I get this message

$ pbiviz start
 info   Building visual...
 error  VALIDATION   Invalid API Version v3.5.0

Hi @Husain - yes, the SDK is a global install so any other projects may be impacted.

In these cases you'd need to reinstall the SDK you want to work with. It's a pain and a large reason why I can't assist on this issue more directly (as I have a huge v3 project that I'm working on at present that I can't deviate from).

This is a problem working with any visual prior to v3 of the SDK, as the API and SDK were bundled together.

For visuals developed on v3 or later the API and SDK are decoupled so it's easier to work across projects on different versions of the API, as you only need to install the necessary version of powerbi-visuals-api local to the project.

If you want to use the same SDK globally for all your projects and work with the sample, you would need to migrate the sample matrix project to support v3 SDK, (or ask MS to do it).

Regarding your follow-on error from the downgrade, if you've re-run npm i from the root of your project to ensure that all packages are correct following the downgrade, then this might need to be rasied as an issue on the repo, or you can try contacting pbicvsupport@microsoft.com to see if the team can assist.

Daniel
