Jenkins says (katalon plugin) job failed, but the tests have all passed


Hopefully, someone understands what I might be doing wrong, or what I should check.

I have a Jenkins instance on a Centos 7 VM. I have had this issues with plugin versions 6.1.5, 6.2.2 and 6.3.0.

The arguments I use to run the plugin are as follows:

-noSpash runMode=console -consoleLog -projectPath=“/var/lib/jenkins/workspace//.prj” -browserType=“Firefox (headless)” -retry=0 -statusDelay=15 -testSuitePath=“Test Suites/Initial”

I have one test in the “Initial” test suite. When I run this job, it passes with:
Test Suites/Initial - Firefox (headless) - 20190821_175841…1/1(100%)

However, the jenkins job says it failed:
Build step ‘Execute Katalon Studio Tests’ marked build as failure
Finished: FAILURE

The test has 77 steps, and I see everyone of them complete:
“2019-08-21 15:55:15.844 DEBUG testcase.ChangePassword - 77: closeBrowser()”

Any help would be greatly appreciated. I am very confused.
