Groovy script getting value from response doesn't work when using testrunner.sh

I am trying to use a script assertion to get a property's value from a SOAP response in a groovy script, verify that value and then write the assertion's result to a local database. All works well (you can see the code posted below) when starting the test case from the user interface. When I start the project from the command line via testrunner however, not so much. For some reason the value I retrieve returns an empty string, thus the assertion always fails. I will also paste the error log below. So here's my question: 

Why can't it retrieve the correct value from the response when using the testrunner? And how can I fix this? 

Thank you very much in advance for your assistance.

 

Groovy Script Assertion:

import com.eviware.soapui.support.XmlHolder
import groovy.sql.Sql

def holder = new XmlHolder( messageExchange.responseContentAsXml )
holder.namespaces["ns2"] = "http://www.tmforum.org/mtop/fmw/xsd/gen/v1"
holder.namespaces["ns10"] = "http://www.tmforum.org/mtop/nra/xsd/cmo/v1"
holder.namespaces["ns4"] = "http://www.tmforum.org/mtop/rtm/xsd/mr/v1"

//Reading regex from the local database using DataSource test step
def regex_Range_HW = context.expand( '${DataSource-actual_run_state#mapping_huawei_Range_HW}' )

//Getting node value from response

def value = context.expand( '${actual_run_state#Response#declare namespace ns2=\'http://www.tmforum.org/mtop/fmw/xsd/gen/v1\'; declare namespace ns10=\'http://www.tmforum.org/mtop/nra/xsd/cmo/v1\'; declare namespace ns4=\'http://www.tmforum.org/mtop/rtm/xsd/mr/v1\'; //ns4:getManagedObjectStatusResponse[1]/ns4:objStatusList[1]/ns10:objectStatus[1]/ns10:statusList[1]/ns2:nvs[1]/ns2:value[1]}' )

//Assertion with regular expression
def regexResult = value.matches(regex_Range_HW)
//Then writing result to database; 

 And here is the error log (it seems to me, that the retrieved value from the response is just an empty string):
