Stock chart throws exception on initial render

Hi,

I'm trying out the Stock chart control and I am unable to get it working on later nuget versions. Just adding the tag makes the circuits break (serverside Blazor). Tried some samples from other posts here on the forum and they work as long as the versions are much older. Any help appreciated.
