Error after upgrading to 3.0.3

Error after upgrading to 3.0.3

crosscuttech opened this issue 8 months ago · comments

After I upgraded to 3.0.3 in my Blazor WASM project, I am getting the following error message in the console:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Watcher error(s): 
      0 > [object Error]: { stack: 'Error: Please provide instrumentation key

I did update the JS code in the index.html.

It is important to note that I am deploying this Blazor WASM app to a few different Azure Storage Accounts with a Static Website. I need to have the ability to customize the App Insights connection string per Storage Account. I have been doing this by replacing a variable in index.html during the publish step in my pipeline. Is this no longer supported?

This was the working code prior to the update:

Can you share your non-working index.html? I suspect something is wrong with your app insights snippet.

Also, are you setting the config programmatically?

builder.Services.AddBlazorApplicationInsights(config =>
{
    // anything here?
});
