I want to use ROOTJS version dev with but recently it cannot work.
I used like：
And the browser is Microsoft Edge version 99.0.1150.55 (64 bit)
It turns waring like：
Uncaught (in promise) TypeError: Failed to resolve module specifier ‘…/modules/core.mjs’. The base URL is about:blank because import() is called from a CORS-cross-origin script.
I can use JSROOT version 6.3.4 with successfully. But TMultrGraph_3d seems not supported in this version(6.3.4)？
In current dev version many changes were done, therefore some application may not yet work.
Are you using https://root.cern/js/dev/? Please try https://jsroot.gsi.de/dev/.
And we will try to solve problem with root.cern website.
