Azure CLI update Log Profiles Error.

Hello Everyone

i'm Trying to update the log-profiles from az-cli but when i want update the locations value i receive a error related with the type of values, the object i'm try to send is an array but the az-cli show an error about this object isn't iterable.

we try this two commands but receive the same error

-- az monitor log-profiles update --name default --set location="eastus" **--set locations="global","eastasia"**

-- az monitor log-profiles update --name default --set location="eastus" **--set locations=["global","eastasia"]**
