QlikView QMS API GetDocumentTask returning null

[SatyaQVT]

Below Powershell script for GetDocumentTask is returning null. RunTaks, AbortTaks, GetTask are working as expected using the powershell. And also Python script for GetDocumentTask is returing all properties of the task. Please help if I am missing something here.

function GetTimeLimSerKey {

    $service = New-WebServiceProxy -Uri $url -Namespace QlikView -UseDefaultCredential

    $service.GetTimeLimitedServiceKey()    

}

function GetDocTaskAll([String]$TaskID) {

    $scope = "All"

    $hdrs = @{}

    $hdrs.Add("SOAPACTION","http://ws.qliktech.com/QMS/12/2/IQMS2/GetDocumentTask")

    $hdrs.Add("Content-Type","text/xml;charset=uth-8")

    $hdrs.Add("X-Service-Key",$serviceKey)

    $body = @{}

    $body = '<s:Envelop xmlns:s="http://schemas.xmlsoap.org/soap/envelop/">

    <s:Body>

    <GetDocumentTask xmlns="http://ws.qliktech.com/QMS/12/2">

    <taskID>' + $TaskID + '</taskID>

    <scope>' + $scope + '</scope>

    </GetDocumentTask>

    </s:Body>

    </s:Envelope>'

    Invoke-WebRequest -Uri $url -Method Post -Body $body -UseDefaultCredentials -Headers $hdrs

}

$url = "http://QDSServer:4799/QMS/Service"

$TaskId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

$serviceKey = GetTimeLimSerKey

$res = GetDocTaskAll -TaskID $TaskId

[xml]$resContent = $res.content

Write-Output $resContent.envelop.Body.GetDocumentTaskResponse.GetDocumentTaskResult

I figured out the issue with the help of my colleague. The parameter should be documentTaskID not taskID.

function GetTimeLimSerKey {

    $service = New-WebServiceProxy -Uri $url -Namespace QlikView -UseDefaultCredential

    $service.GetTimeLimitedServiceKey()    

}

function GetDocTaskAll([String]$TaskID) {

    $scope = "All"

    $hdrs = @{}

    $hdrs.Add("SOAPACTION","http://ws.qliktech.com/QMS/12/2/IQMS2/GetDocumentTask")

    $hdrs.Add("Content-Type","text/xml;charset=uth-8")

    $hdrs.Add("X-Service-Key",$serviceKey)

    $body = @{}

    $body = '<s:Envelop xmlns:s="http://schemas.xmlsoap.org/soap/envelop/">

    <s:Body>

    <GetDocumentTask xmlns="http://ws.qliktech.com/QMS/12/2">

    <documentTaskID>' + $TaskID + '</documentTaskID>

    <scope>' + $scope + '</scope>

    </GetDocumentTask>

    </s:Body>

    </s:Envelope>'

    Invoke-WebRequest -Uri $url -Method Post -Body $body -UseDefaultCredentials -Headers $hdrs

}

$url = "http://QDSServer:4799/QMS/Service"

$TaskId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

$serviceKey = GetTimeLimSerKey

$res = GetDocTaskAll -TaskID $TaskId

[xml]$resContent = $res.content

Write-Output $resContent.envelop.Body.GetDocumentTaskResponse.GetDocumentTaskResult
