I have also modified the comment to explain
returnData: entry.tag ? undefined : falsebut I endeavor to explain even more here. Only 1 metric within an expression can havereturnData = true; the rest must befalse. Cloudformation also defaults an undefined return data totrueas long as the rest are set tofalse, which is why this ternary operation works. The idea behind this line is thatentry.tagis defined (with a default oftrue) for the top level expression only and thus every other metric within the expression hasreturnData = false.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license
