Provide object property docs for az apic api update --custom-properties + example

[neilpeterson]

I am trying to add custom data to an API with the Azure CLI and cannot get the shorthand syntax correct. Are there properties and / or examples that can be added to the CLI docs / help to assist?

CLI help output

PS > az apic api update --custom-properties ??

Argument
    --custom-properties : Object
        The custom metadata defined for API catalog entities.
        See https://github.com/Azure/azure-cli/tree/dev/doc/shorthand_syntax.md for more about
        shorthand syntax.

Object Properties

I've tried several things, based on the REST spec this seems most likely. Notes, the API schema has been updated to include internal_id.

az apic api update -g $API_CENTER_RESOURCE_GROUP_NAME -s $API_CENTER_INSTANCE_NAME -w default --name $APICAPIName --custom-properties "{properties:{internal_id:'3c3544e5-d623-4650-aaa4-b06c5467f162'}}"

However, this results in the following error.

Failed to parse '--custom-properties' argument: Shorthand Syntax Error: Expect character ',' or ']':
        {properties:[internal_id:

Thanks a bunch.

Regardless of updating the docs, any hint here would be helpful. Struggling to get this working :)
