crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]

I’m getting this exception in the browser console window:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Method not found: int Bolero.Node.Invoke(object,Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder,Microsoft.FSharp.Core.FSharpFunc`2<System.Type, System.Tuple`2<int, Microsoft.FSharp.Core.FSharpFunc`2<object, int>>>,int)
System.MissingMethodException: Method not found: int Bolero.Node.Invoke(object,Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder,Microsoft.FSharp.Core.FSharpFunc`2<System.Type, System.Tuple`2<int, Microsoft.FSharp.Core.FSharpFunc`2<object, int>>>,int)

I was able to reproduce it by taking a copy of the HelloWorld example project I had lying around, which was working fine, and then doing a dotnet paket update. But then, if I revert my changes, the problem does not go away. Here is the packet.lock file at the time it was working, before I did the dotnet paket update:

STORAGE: NONE
RESTRICTION: == net7.0
NUGET
  remote: https://api.nuget.org/v3/index.json
    FSharp.Core (7.0)
    FSharpPlus (1.3.2)
      FSharp.Core (>= 6.0.6)

After the dotnet paket update, it changed to this:

STORAGE: NONE
RESTRICTION: == net7.0
NUGET
  remote: https://api.nuget.org/v3/index.json
    FSharp.Core (7.0.200)
    FSharpPlus (1.3.3)
      FSharp.Core (>= 6.0.6)

This is when the problem started, but like I said, if I revert my paket.lock, the problem is still there.

I’ve tried dotnet paket clear-cache --clear-local and dotnet tool restore and dotnet paket restore but nothing helps. Once the problem is there, I can’t seem to get rid of it.

I’ve no idea whether this is a Bolero issue, or a Paket issue, or a Blazor WebAssembly issue, but I thought I’d post here to start with.

I have now published HotReload 0.21. Can you try and update Bolero and HotReload to 0.21? I expect it should fix this issue.

Ah, I think the problem is that indeed the type Node has changed in v0.21, but the HotReload packages haven’t been updated to match. I’ll unlist v0.21 immediately, and restore it once I’ve updated HotReload (and done the release announcement 😄)
