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

[sarafamiglietti]

Hello,

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.

Error

The 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?

Thanks&Regards

Sara

Actually, It was worst after creating a local user.

I had a lot of Directory Service Connector problem.

After reading this post:

Directory Service Connector is offline

The reason was : "this appears to be a domain policy that will not allow a non-domain user to query the AD. I have seen this in the past".

So back to the square one...

Hello,

On the Server, there were two .NET Framework versions installed : 3.5 and 4.5.

As Qlikview uses .NET Framework 4.0 which is included in 4.5 version (See Qlikview Server > System > About), we uninstalled .NET Framework 3.5 and we no longer had the problem!!!!!!!

Problem solved!
