    How to Solve : Qlikview system.argumentnullexception value cannot be null

    Sara Famiglietti



      I have a task which is scheduled several times a day and which works fine but sometimes an error occurs randomly.

      I searched on the community how to solve this problem without success.


      ErrorThe task "XXXX.qvw" failed. Exception: || QDSMain.Exceptions.TaskFailedException: Task execution failed with errors to follow. ---> System.ArgumentNullException: La valeur ne peut pas être null. || Nom du paramètre : stringToUnescape ||    à System.Uri.UnescapeDataString(String stringToUnescape) ||    à QDSMain.DistributeTask.GetFileName(String path) ||    à QDSMain.DistributeTask.Execute(TaskResult currentTaskResult) ||    --- Fin de la trace de la pile d'exception interne --- ||    à QDSMain.DistributeTask.Execute(TaskResult currentTaskResult) ||    à QDSMain.Task.AbstractTask.TaskExecution(ILogBucket logBucket, TaskResult taskResult)


      Qlikview version : 11.20 SR12

      Operating system : Windows Server 2012 R2 Standard (64 bit edition).


      Can someone help me?
