Cannot write metadata to root object

[drewcassidy]

Describe the Bug

I have the following call. The input items are batched so "VersionFIle" at this point is a single item. it does have the "a" metadata variable

    <JsonPoke Content="{}" Query="$" Value="@(VersionFile)" Properties="a">
      <Output TaskParameter="Content" PropertyName="_JSON"/>
    </JsonPoke>

Expected Behavior

Output json would be

{
  "a": "Value of a"
}

Exception with Stack Trace
