The $wsapi_version variable is set to both 1.43 and v2.0 in my_vars.rb.
We need to ensure that it is set to '1.43', and not 'v2.0' (or comment out its definition in my_vars.rb). If we not do this, this we get error while running user_permissions_summary.rb.
Same may be the case for the other scripts too.
At the least, this needs to be documented in the Readme instructions.
