Label is ignored/incorrect in resource picker parameter (from JSON)

Question

Hi,

I've followed the documentation: Create a JSON list resource parameter (Content source) to create a parameter of type Resource picker. The name of the parameter is Applications and the data comes from a JSON list with labels defined (content is the one from the example):

[

    { "value":"/subscriptions/<sub-id>/resourceGroups/<resource-group>/providers/<resource-type>/acmeauthentication", "label": "acmeauthentication", "selected":true, "group":"Acme Backend" },

    { "value":"/subscriptions/<sub-id>/resourceGroups/<resource-group>/providers/<resource-type>/acmeweb", "label": "acmeweb", "selected":false, "group":"Acme Frontend" }

]

In the next Resource parameter options section, the value for {Applications:label} is shown to be acmefrontend (or acmeauthentication). However, all I get in the preview AND when used in a query is this: /subscriptions/<sub-id>/resourceGroups/<resource-group>/providers/<resource-type>/acmeauthenticatio

This query

traces

| where message == {Applications:label}

is translated to this:

traces

| where message == /subscriptions/<sub-id>/resourceGroups/<resource-group>/providers/<resource-type>/acmeauthentication

All works fine if the type is changed to Dropdown, however, for my workbook I really need the Resource picker type. This is incredibly frustrating..
