Faiure Importing Sessions with Arbitrary Import Script

[DCiscoKid]

When using the ImportArbitraryDataFromFileToSecureCRTSessions.py script on MacOS, I am now getting the following message, where I was able to do this previously:

Error: Unknown field designation: session_name
Supported fields are as follows:

description,emulation,folder,hostname,port,protocol,session_name,username,logon_script

I am at a loss to understand why this has started failing.
