 Hi @khawaga, and welcome to WordPress Trac!

 To add custom messages for validation errors, be sure that the
 `validate_callback` adds error messages to the `WP_Error` object passed to
 it. For more details, [https://make.wordpress.org/core/2016/07/05
 /customizer-apis-in-4-6-for-setting-validation-and-notifications/ see the
 dev note] written when the validation API was added to core.

 Please also note that support for custom development isn't available here
 in Trac. If you have more questions about your project,
 [https://wordpress.org/support/forum/wp-advanced/ you'll be able to find
 help in the support forums].
