Hey

Sorry, I don't know how to go further here, i found uuid support in the changelog, but yet

(byebug) parent_task.children.create(user_id: parent_task.user.id, workflow_id: parent_task.workflow.id)
*** ActiveRecord::StatementInvalid Exception: PG::UndefinedFunction: ERROR:  operator does not exist: uuid = integer
LINE 5: WHERE x.descendant_id = 72337
                              ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.
: INSERT INTO "task_hierarchies"
  (ancestor_id, descendant_id, generations)
SELECT x.ancestor_id, '2cd4eac4-322c-47d7-91a9-73cf95eead48', x.generations + 1
FROM "task_hierarchies" x
WHERE x.descendant_id = 72337

rails 5.2.2
closure_tree-7.0.0

I will appreciate every help very much
