Blazor hosted client - error on published web application on azure app service

When calling the xxxxxxxx.azurewebsites.net, the following appears in the browser console. Can anyone help. Thanks.

I've got this error while migrating the blazor application to .net6. Installing Hosting Bundle Installer on application server, resolved the issue.

I updated all my code the the release version of the web assembly which gave no error in development mode on my pc but errors when publising it to azure.

The problem was with Microsoft.AspNetCore.SignalR.Client in the web assembly. Removing the package and code related to the package did not generate any errors.

I fixed the problem by using the javascript SignalR in my web assembly. It works but I would have prefer to use the package SignalR and the C# code to handle the connection instead of using javascript.

Note: I tried the package with only a web assembly (instead of a hosted web assembly). Same errors with the package when published to azure.

This looks like a linker issue. Does it work if you disable linking?

<PropertyGroup>
  <BlazorWebAssemblyEnableLinking>false</BlazorWebAssemblyEnableLinking>
</PropertyGroup>

Also you are using the older (Microsoft.AspNetCore.Components.WebAssembly" Version="3.2.0-preview5.20216.8") version of WebAssembly.

I would suggest to upgrade to latest version.

<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="3.2.0" />

You may also try clearing cached files locally.
