Help - "Error: The task "System/QlikView Directory Browser.qvw" failed"

[#1]

Hello,

Our Qlikview sever appears to have been failing to load the Directory Browser file and Ops Monitor file (which are scheduled per day and per hour respectively) for the past few days. Despite my best attempts to understand what is going on through looking at the log files etc. on the QV Management Console, as well as checking for hints/suggestions/advice on this forum, I have reached the end of my limited knowledge and cannot get any further.

I dont think the problem lies with the webserver on which it is hosted, as I can gain access to it via a remote desktop connection. Indeed, looking at the log files, the problem seems to be with a Null Exception occurring at some point. However, not being able to debug, it is close to impossible to identify where the problem lies.

Also, I have been able to run the files in question manually without any problem, so dont think they are necessarily at fault. I have posted the key aspects of the error messages for the two files below

Any help you might be able to provide will be greatly appreciated.

Thanks

Did you run the report on the client on the server or on your computer?

Hi Markus,

The report was run in the QV Management Console on the (third party) server, which I connected to via Remote Desktop. If that is what you mean.

Incidentally, I just spoke to them (the owners of the server) and they pretty much said the fault lies with the software, i.e. QV, which is what I guessed anyway.

I would recommend checking all connection to data sources of the report. In order to exclude connection or right problems as possible source of error.

If that not help contact the QlikView Support.

The task logs unfortunately seldom says anything about what actually goes wrong in the logic. It is better that you turn on document logs (open a document in Desktop -> Document Settings -> Generate Log file). Then you can see where in the script it fails. Hopefully that tells more about what file/connection is not working.

Thanks Morgan, ill give it a go and hopefully come up with something helpful!
