In my blazor-server-side app I am calling JSRuntime.InvokeAsync to open static content in a popup window:
await _jsRuntime.InvokeAsync<object>("open", "/help/help.html", "_blank");
It works, but after some time (probably a timeout?) a TaskCanceledException is thrown. I tried calling InvokeVoidAsync, but the effect is the same. I can fix this by catching and ignoring the exception or by removing "await", but I was hoping for a cleaner solution that does not give me complier warnings.
Try specify cancellationToken as CancellationToken.None
await _jsRuntime.InvokeAsync<object>("open", System.Threading.CancellationToken.None, "/help/help.html", "_blank");
A cancellation token to signal the cancellation of the operation. Specifying this parameter will override any default cancellations such as due to timeouts (DefaultAsyncTimeout) from being applied.
To resolve the compiler error, use discard '_':
_ = _jsRuntime.InvokeAsync<object>("open", "/help/help.html", "_blank");
