@mrnams Not finish yet, maybe need some help too.

Do you have user agent string? I would like to test this out. Thank you very much

Very interesting, what is the user agent? Do you have logs?

I just need the user agent that are causing the problem to use unit testing

I don't any wrong with this user agent. I would do further investigation later this even. 

@BobBonser Are you still see this issue with Detection 5.0 release?

Interesting, but why would UserAgent be empty if the client is not sending any. Is this a bug that causing your web application to crash not just create event logs....

Very interesting investigation, let me study more about WebSockets. Maybe if need to check it must enable checking too. https://docs.microsoft.com/en-us/aspnet/core/fundamentals/websockets?view=aspnetcore-6.0

Any progress regarding this issue? Its would make DocFX features extendibility top out everything.

I hope you like this fixed i have made for tabler. everything looks good to go now. https://tabler-git-fork-wangkanai-card-tabler-ui.vercel.app/form-elements.html?theme=dark
