Pbiviz start @ [email protected]

Hi! thank you for answering me!

I've already tried installing the packages at the latest version but didn't work , since the project is built for pbi visual tools 2.5.0. Even upgrading pbiviz@latest the visual remains blank with the error shown here https://community.powerbi.com/t5/Desktop/Power-BI-version-doesn-t-support-custom-visual-sampleBarChart/m-p/463943 .

As the project author suggests the visual works specifically at the pbiviz 2.5.0 version here https://github.com/xiaodongliang/forgeviewer_embed_in_powerbi_report 

and here  https://forge.autodesk.com/blog/embed-forge-viewer-inside-power-bi-report 

My fear is that i have to change something right in the prerequisite packages , maybe even Typescript, but i can't get which is the right version to look for. 

Any suggestion woul be precious

Thank you!
