I am no expert in PXP, but this error message simply tells you that
you are passing a function where a node is expected (unfortunately you
didn't show the position highlighted by the error).
Looking at the type of find in the PXP manual, it looks like your
"collectors" is a function.
This kind of thing can happen when using let...in and forgetting an
argument; it gets a bit of habit to see what can cause an error.
