How to debug a web-proxy url on Fortigate

[ZANOOB]

I am using the following https://kb.fortinet.com/kb/documentLink.do?externalID=FD40540

To run a debug for the url for a user.

However, when i run the command "diagnose wad debug-url enable"I get the following error message.

 $ diagnose wad debug-url enable

 

command parse error before 'debug-url'

Command fail. Return code -61

 

I configured the web-proxy with the requried url and still the same error. Is there a way to debug a url on Fortigate proxy ?

 $ show web-proxy debug-url 

config web-proxy debug-url

    edit "zoom.com"

        set url-pattern "*.zoom.com"

    next

end
