Semi-random JsonException thrown from EndInvokeJS

See original GitHub issue

Describe the bug

In some random cases, Blazor JSInterop throws JsonExceptions. I didn’t find a way to create a minimal reproduction, since this appears to be a timing issue which is super hard to reproduce. Moreover, it happens at different points on my versions of Chrome & Firefox, and changes (pass on one page previously failing, & fail on page previously passing) depending on Task.Delay()s. So, yeah, a repro gonna be hard. Yet, I think I could give you access to my full app where the error occurs.

This is probably a continuation of #34267

So I’ve tweaked around, cloned aspnetcore entierly & built it locally to test some little things. And I’ve managed to track it down to this:

My error was thrown here:

https://github.com/dotnet/aspnetcore/blob/ae1a6cbe225b99c0bf38b7e31bf60cb653b73a52/src/JSInterop/Microsoft.JSInterop/src/Infrastructure/DotNetDispatcher.cs#L311-L314

I’ve found out that an entire JSON object was still pending for read in the JsonReader.

So I’ve digged deeper to here:

https://github.com/dotnet/aspnetcore/blob/ae1a6cbe225b99c0bf38b7e31bf60cb653b73a52/src/JSInterop/Microsoft.JSInterop/src/JSRuntime.cs#L228-L235

So, if the invocation timed out (or whatever, but yet, the task is not there anymore), the stream is let as-is, untouched, with data pending.

I’ve managed to reliably fix my issue by adding jsonReader.Skip() before here: https://github.com/dotnet/aspnetcore/blob/ae1a6cbe225b99c0bf38b7e31bf60cb653b73a52/src/JSInterop/Microsoft.JSInterop/src/JSRuntime.cs#L234

I don’t know if it makes sense. I don’t have a repro, but at least, you might have more clue about the underlying problem.

Good news ! It seems that it fixed the main issue !

Now, the surprise is to see if it solved also other errors scattered around my project 😃 good job and thank you very much 😃 hope this gets approved soon !

So,

I’ve edited here

https://github.com/dotnet/aspnetcore/blob/591391e425659ab618f5e2f891396ac3e34cf264/src/JSInterop/Microsoft.JSInterop/src/Infrastructure/DotNetDispatcher.cs#L313

And replaced with

                throw new JsonException($"Invalid JSON. Arguments were: `{arguments}`");

Here’s my exception now:

Uncaught (in promise) Error: System.Text.Json.JsonException: Invalid JSON. Arguments were: `[18,true,{"x":0,"y":104.5,"width":240,"height":162,"top":104.5,"right":240,"bottom":266.5,"left":0,"scrollY":0,"scrollX":0,"windowHeight":873,"windowWidth":1824}]`

OFC, feel free to remove unrelevant data.

                // We should simply return if we can't find an id for the invocation.
                // This likely means that the method that initiated the call defined a timeout and stopped waiting.
                return;

                succeeded = succeeded,
                existed = true,
            });

Please don’t pay attention to the dirty calls I made to fetch token from session storage manually. Using the normal authentication service triggered an error almost every time, and now that I’m thinking about it, it might be related to this issue too. But I left those calls in the record above so that you can see every calls made.

So I think that the error is that taskId 18 in the record is cleaned up before End. An uneducated thought of mine would be that it’s a race condition that might be tangled with how JS engines handles tasks queues under the hood, since I have been in a state where Chrome & Firefox did both trigger the error, but not on the same page, thus not with the same timing/calling order. Unfortunatelly, I can’t get you records of that state for both browsers. My DB has been modified since, and I can’t rollback to that exact state.

Let me know your thoughts if you have a couple of minutes 😃
