When we tried to run the script te_asset.py we expected an error where it said that no data was retrived from the "make" field.
When looking in to the XML from Tripwire we noticed that we hade some nodes that was setup with a SSH connection and the "make" field in the XML was empty. This caused the script to fail since there is no error handling in the script.
By altering the script with an try and except field the script ran without any issues.
You might want to update the script so it has a better error handling.
