Vector tile layers not loading in new map viewer

GB_MattPanunto_GISS

I wrote a script that adds several vector tile layers to a web map via ArcGIS API. However, these layers aren't displaying in the new map viewer, and just say "An error occurred loading this layer". They display just fine in Map Viewer Classic though. They are all published in Web Mercator Aux Sphere projection. Any ideas? Using ArcGIS Pro v3.1.1.

It's actually a known bug, I forgot to update this post. See this thread:
