I try to send a cancellation request from Angular client (use Observable -> unsubscribe) to cancel long Task Operation but API not fire.
[HttpPost]
public async Task<GetDataOutputDto> GetDataLongOperation(CustomInputDto input)
{
try
{
var tokenSource = new CancellationTokenSource(); // _httpContextAccessor.HttpContext.RequestAborted;
tokenSource.CancelAfter(2500);
var token = _httpContextAccessor.HttpContext.RequestAborted; //tokenSource.Token;
var settings = new JsonSerializerSettings
{
Error = (sender, args) => {
args.ErrorContext.Handled = true;
},
MissingMemberHandling = MissingMemberHandling.Ignore
};
//... remove for brev
}
on angular side
this.subscription = this.loadData(undefined).subscribe(res=>{
console.log('data loaded!');
this.localData = res.data;
//this._rawData = this.localData;
this.loadItems();
});
setTimeout(() => {
console.log('TEST stop long')
this.subscription.unsubscribe();
}, 2500);
I test that if I use TaskSource with CancelAfter all code behind work well but from web (client side) I can't fire the cancellation operation

Hi @ismcagdas
I found a solution but is not related to a ABP/Zero bug Framework all depends in wich way Angular close / cancel connection.
In any way I use this solution angular-how-to-cancel-http-calls-on-router-change
I put it on root.module.ts so now when user change route all connection receive cancellation and it close the flow if is implemented.
