WLST & ALSB AttributeError: 'None' object has no attribute 'exportProjects'

Question

I have the following WLST script that exports an ALSB 2.6 project and a Customization file for that project. The script was downloaded from the BEA website sometime ago, and I had it working fine. A recent change broke it, and I'm not sure why. I'm hoping someone can help me out here...
The script is below:

     When I connect to the admin server using the "connectToServer" command (commented out in the code above) the script works fine. When I tried to use the "connect" command, using a connect.properties file instead of a plain text userid and password, the line:
     <strong>theBytes = ALSBConfigurationMBean.exportProjects(collection, passphrase)
     </strong>fails and I get an error that says: <strong>AttributeError: 'None' object has no attribute 'exportProjects'
     </strong>Can someone explain to me the difference between these two commands, and if there is anything I can do to tweak this code to get it working using 'connect' vs. 'connectToServer' syntax?
