when run the same command with of the json from examples it generated the classes without any error.
Can anybody help me understand what I might be doing wrong or if I am missing something?
I have installed LUISGen with below comand dotnet tool install --global LUISGen --version 2.2.0

Normally I would say 'make sure you're using the most up-to-date version of the tool', but
LUISGen is deprecated (legacy tool). The new botframework-cli was designed to replace legacy standalone tools. I don't think you're missing anything, but it hasn't been updated in almost a year.
The botframework-cli has a similar command: bf luis:generate:cs meant to generate CS classes on LUIS models.
