The swagger format was not "required":true

[BethanyZhou]

I remember you said it's required in your manual test?

[lijinpei2008]

Yes, but in fact, in the example I provided, all of the parameters used are required.
I am now ready to mark these parameters "Mandatory" under the Custom folder

[BethanyZhou]

I can't find it's mandatory in the syntax of New-AzGrafana.md

[lijinpei2008]

Update some parameters and mark them as required
