Description
Is there an existing issue for this?
- I have searched the existing issues
Describe the bug
Calling an asynchronous .NET JS Interop method synchronously produces an unhelpful/misleading error message.
These error messages (shown in steps to reproduce section) makes debugging the problem not very clear and seem mostly related to JSON Serialization - whereas that might not be the case.
Expected Behavior
Error message should indicate that this is an (unsupported workflow?) and warn against invoking async methods synchronously from JS or something that makes it easier to identify what the issue is.
Steps To Reproduce
Repo reproducing problem here: https://github.com/daytonjallen/JsonExceptionRepro
- Start new blazor wasm project
- Create async JSInvokable method from C#
- Call the above method from JS synchronously (DotNetObjectReference.invokeMethod)
Functions executes "successfully" and produces an exception in the console:
Also the error is different if we pass parameters:
