QMS v11: Issue with GetTaskStatuses

dvasseur — Mon, 26 Jan 2026 18:19:17 GMT

Hello,

I've a strange error while using GetTaskStatuses on a QV11 server.

The code:

TaskStatusFilter taskStatusFilter = new TaskStatusFilter();

taskStatusFilter.EnabledState = EnabledState.Enabled;

List<TaskStatus> taskStatuses = BackendClient.GetTaskStatuses(taskStatusFilter, TaskStatusScope.All);

Error:

Message: System.NullReferenceException: Object reference not set to an instance of an object.

I've also tried with the QMS API Client, same error

Any clue ?

What does the GetAlert() respond? Have any service issues in the QMC? Any other errors in the QMS log, or any other service log?

GetAlertText() => empty string

No issue in the QMC and nothing in the QMS log (debug mode) nor in any other log (I'm not sure for QDS, there are many log files, which one should I check ?)

BTW I'm using a QVS without Publisher

You know what? I'm actually getting it in my server as well. And I even have Publiser. I'll try some more in the morning.

David, this seems to be a bug and I have reported it as one. Please create a support case with QlikView Support (and make sure to reference me in it), so I can attach it to the bug and get the proper priority.

Unfortunately, I see no workaround for this issue at the moment.

Thank you!

I'm reporting this on 11 SR1, by the way.

Thanks in advance.

It look like it's listed in beta QV 11.2 release as corrected :

bug 47503

GetTaskStatuses call in QMS API returns System.NullReferenceException

Hi All,

I have hit the same bug doing testing for our 11.0 SR2 upgrade. I can see the release notes for 11.2 IR say this bug has been fixed. Have you upgraded and tested it yet? If so, did the 11.2 release introduce any more QMS API bugs you have noticed?

Thanks

I've heard rumours that this is not fixed, yes, but I haven't verified myself yet, so I can't say. I'll test it tonight and get back to you guys.

Yes, the issue still seems to be apparent. I'll check the fix.

Hi Stefan,

Do you mean that the bug still exists in 11.2 IR? Accorging to the release notes it has been fixed:

47503 GetTaskStatuses call in QMS API returns System.NullReferenceException

It definitely exists in 11.0 SR2 - that's where I'm hitting it.

Thanks

Graeme

This is what I'm trying to figure out. It is documented as fixed in SR2, but it isn't. It might be included in 11.20 IR though, but I'm trying to verify.

For the anyone else stumbling across this thread...I can confirm this is working in 11.2 IR, but not in 11.0 SR2.

Thank Graeme

I can confirm that the the issue is still in 11.00 SR2 11440, I'vs just got it.

(but it look like less frequent than in previous version).
