Hello

When trying out the asserts example from the doc:

(xt/submit-tx
    node
    [(-> (xt/assert-not-exists '(from :users [{:email $email}]))
         (xt/with-op-args [{:email "james@example.com"}]))
     (xt/put :users {:xt/id :james, :email "james@example.com"})])

it throws an error:

1. Unhandled java.lang.AbstractMethodError

I’ve upgraded to xtdb v2.0.0-20240131.134947-5 released yesterday and happy to report that the new ops :assert-exists and :assert-not-exists now works as advertised.

Thanks!
