terminated circuit

Getting this error when I try to display a pdf.  Happens in app when I deploy to IIS, but works fine in visual studio. Pulling what's left of my hair out. 

*****************************************************************************************

blazor.web.js:1 [2026-02-02T05:08:36.359Z] Error: There was an unhandled exception on the current circuit, so this circuit will be terminated. For more details turn on detailed exceptions by setting 'DetailedErrors: true' in 'appSettings.Development.json' or set 'CircuitOptions.DetailedErrors'.

Hi gary rose,

Thank you for the update. Please check the detailed errors you are encountering by adding the following configuration in your appsettings.Development.json file in your Blazor project:

 

{

 "DetailedErrors": true,

 "Logging": {

   "LogLevel": {

     "Default": "Information",

     "Microsoft.AspNetCore": "Warning"

   }

 }

}

 

After enabling this, kindly share the complete error details with us.
 

Additionally, please modify the attached sample to replicate the issue you are facing with the PDF Viewer using your code.
