APPIAN RPA - IBM 3270 Workflow Library - Issue with set emulator and connect to Emulator

Hello,

Am working on Appian RPA POC to connect to Mainframes systems through Bluezone client.

For this am using the IBM 3270 workflow library provided by Appian. Am facing issues with methods(Set Emulator & Connect to Emulator).Set emulator from V1.0 library and connect to emulator from V2.0 library both are failing.

Set Emulator Error:
