It seems, we have included a wrong example set for 'UUID', so I have corrected the same. Thanks for looking into this

[bigludo7]

Could someone help me to validate the Linter errors that coming up ?

The error was on the uuid ?
I saw a lot of warning but only one error

Anyway seems you solved it ;)
