Hello dear support. I'm trying the 19.4 today, after update from 19.3, and I start getting multiple reports on this error

But... It is there.

I just opened You sample with Visual Studio, and run it without any kind of modifications, and the exception popped up:TypeError: Cannot read properties of undefined (reading 'show')

Hi Yordan, 

We were unable to reproduce your reported problem at our end. Can you please find the below video for your reference? 


We suspect that you have enabled the IgnoreScriptIsolation set to true in the Program.cs file. So, you need to properly reference the script file like below. 

If you still have an issue, could you please share the below, 
  • Please share the video with your issue for better understanding.
  • Did you manage to open the Blazor Dialog component?
  • Have you used .NET 6 or .NET 5?
 
Regards, 
Buvana S

I really sorry that I took You time this way.

Seems like I've missed this part.

Thank You  Buvana S !

I also am getting this- I do not have EnableScriptIsolation set to true:


I get a few different exceptions, all from the above mentioned dll:



I believe I have properly brought in the script:


This is a .NET Core 3.1 app, currently porting to .NET 6 where I also see the same exceptions.


Any ideas on where to look?
