Command output is not clear when invalid parameters are provided

[miler-glades]

Description

When running a command with invalid parameters, the output is not clear about what went wrong. It’s difficult to understand which parameter is causing the issue, leading to unnecessary troubleshooting.
Run any mesh-cli command with an invalid parameter. The error message is unclear and doesn’t specify what part of the command is invalid.

Proposed solution

Improve the error message to indicate exactly which parameter is incorrect or missing, making it easier to identify and correct the issue.
