Can not enable user_limits feature flag in RabbitMQ 3.9.15

[Regmir]

Hi, we want to upgrade our RabbitMQ to 3.11 version from 3.9.15. To be able to do that we want to enable user_limits feature flag, which currently disabled, with command rabbitmqctl enable_feature_flag user_limits. Unfortunately we got following responce:

Enabling feature flag "user_limits" ... Error: {'Bad transform function', :rabbit_user, #Function<2.57929690/1 in :rabbit_core_ff>, :"[email protected]", {:badfun, #Function<2.57929690/1 in :rabbit_core_ff>}}

Perhaps someone has already encountered a similar problem? Perhaps someone knows what the problem might be and how to solve it?
