Hopefully @jolly-midnight-72759 @damp-quill-59187 no one will deal with the same confusing error message you both had, after this PR. https://github.com/pantsbuild/pants/pull/11081 Feedback appreciated on the PR description about the wording of the new error message!

The "After" error message is clearer. There is still some ambiguity about which input is at fault. Is

UnexpectedTargets

supposed to be a single object of type

Addresses

or the

Addresses

part? I guess it is "obvious" that it is the

Addresses

part. Is it true that `Get(A, B)`expects

A

to be of type

UnexpandedTargets

and

B

to be of type

Addresses

? If yes, then maybe:

Exception: Invalid input to `Get(A, B)`. Expected `B` to be of type `Addresses`, but got value `int` of type `int` instead.
