Strange issue when running Jmeter and kloadgen plugin

[hedes-gs]

Hello
i've jus started to use kloadgen and Jmeter when running the test in the Jmeter GUI . The test is failing (maybe normal, but I do not know why ) and after that there is the following exception :

2023-09-28 12:51:03,512 ERROR o.a.j.t.JMeterThread: Test failed!
java.lang.NullPointerException: Cannot invoke "org.apache.jorphan.collections.HashTree.traverseInto(org.apache.jorphan.collections.HashTreeTraverser)" because "treeItem" is null

Version of jmeter : 5.5
KloadGen : 5.6.7
jdk : 17

Any idea ?
Thanks for your help
