There was a problem hiding this comment.
The "elements" of a set are the conceptual placeholders for the value (in the implementation, Element() actually returns the key-value pair), but it is still a "value" which is derived from an expression. I see how the wording above is a bit clumsy with the repeated use of "value", but I don't think this is more clear. That could be because I'm used to communicating in Terraform's language, so I wonder if anyone else find this problematic enough to change.

Given the comment from @jbardin and no further follow-up, I'm going to close this one. Thanks for this submission, I think we would still be open to some manner of clarification of this language. |

The wording of this error is confusing, it mixes the "values" of a set, and the "values" of a map. I have reworded to make it clear what is being talked about - the "elements" of a set, and the "keys/values" of a map.
This change only affects the error messaging, and nothing else.
