Log.SaveResultsAs() does not appear to be saving results

I'm relatively new to TestComplete and am trying to export a JUnit summary after my test suite completes. The test suite executes automatically on a remote node so I cannot save the results manually. I have tried adding the following script test to perform the task:

def StoreJUnit():
    sPath = "C:\\<some path>\\test_summary.xml"

    # Store JUnit test results in the project directory
    Log.SaveResultsAs(sPath, lsJUnit, False, lesFull)

I can create .txt files in my test so I know it is executing but have been unable to produce the desired JUnit summary.
