Python script to open Teststand seq files

Hi,

I am using python to open very simple teststand seq file as shown below:

import win32com.client

try:
    tsEngine = win32com.client.Dispatch('TestStand.Engine.1')

    sequencePath = 'Sequence File 1.seq'
    seqFile = tsEngine.GetSequenceFileEx(sequencePath)
    execution = tsEngine.NewExecution(seqFile, "MainSequence", None, False, 0)
    execution.WaitForEndEx(60000)
print(execution.ResultStatus)

    released = tsEngine.ReleaseSequenceFileEx(seqFile, 0x4)

except Exception as ex:
print(ex)

Using the above code, I am able to open the seq file, and get the ResultStatus at the end of the execution.

After that, I called ReleaseSequenceFileEx() to release the reference to the seq file.

However, I encountered the following Teststand's warning very frequently.

Please help.

The Engine.ReleaseSequenceFile(Ex) method was not called for the following files:
    C:\Program Files\National Instruments\TestStand 2016\Components\Callbacks\Station\StationCallbacks.Seq
    C:\Users\Public\Documents\National Instruments\TestStand 2016 (64-bit)\Components\Callbacks\Station\StationCallbacks.Seq


References to PropertyObjects were not released properly.
    Total number of objects: 228
    Number of top-level objects: 19

    Note: Some top-level objects may be included if they are referenced by
    an incorrectly released top-level object. For example, an unreleased
    SequenceContext object references a SequenceFile object.

    The following top-level objects were not released:

        Executions [1 object(s) not released]


        Files [2 object(s) not released]
            SequenceFile #1:
