I am having this issue in SP Workflow 2013 that every time it executed , it always goes to Suspended stage.
However, I do not have any HTTP calls in the workflow. Its just getting current item value. Refer below.
RequestorId: 6ad701cc-759b-fdb1-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.IO.InvalidDataException: Unable to deserialize HTTP response content. Expected ContentType : 'application/json', 'text/plain' or 'text/html', Received ContentType : 'text/html'. Content (truncated) : ' '. ResponseStatusCode : 'OK' Request Uri : 'https://website.com/sub/subsite/_vti_bin/client.svc/sp.utilities.utility.ResolvePrincipalInCurrentcontext(input=@ParamUser,scopes='15',sources='15',inputIsEmailOnly='false',addToUserInfoList='False')?@ParamUser='i:0%23.w|group\sakthi'' at Microsoft.Activities.Hosting.Runtime.Subroutine.SubroutineChild.Execute(CodeActivityContext context) at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager) at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)
