Raw Warning
Duplicate relation "guilds" in a relation expression. You should use "a.[b, c]" instead of "[a.b, a.c]". This will cause an error in objection 2.0
Can somebody explain what this is ?
I cannot explain it better than that error message. a is the duplicate relation in that error message.
I know it is a bit late, but but please check if you have the duplication within you eager() option. We had the same issue for model.query().select("...").eager(something, a, a.b)
