I have a 2013 workflow on my 2016 on-premise farm, which sends emails. Today suddenly it stopped working and now it throws the following error:
System.Net.WebException: Exception encountered while processing the HTTP request. Exception details: 'HttpClient.SendAsync task was canceled. TraceActivityId=df66ae7c-8ca8-56d0-a2f9-d58625db1b8a'.
at Microsoft.Workflow.Common.AsyncResult.End[TAsyncResult](IAsyncResult result)
at Microsoft.Activities.Hosting.HostedHttpExtension.HttpRequestWorkItem.OnEndComplete(ScheduledWorkItemContext context, IAsyncResult result)
However, It does send the email, the user receive it, but the workflow is in a sort of loop and sends the email each minute until the workflow is not cancelled by the user. No changes have been done to the workflow, neither updates installed. Can't find any information on the web.
I tried to reproduce the issue, calling the endpoint using Postman. The endpoint works, I get 200, receive the email, however the call lasts 1minute and the result is:
{
"d": {
"SendEmail": null
}
}
Is this correct? If I take a look into the API, SendEmail should return true or false...
