Undefined is displayed if there is a problem.
My solution: delete the plugins in the DEps folder and copy them again. /home/emqx-rel-2.3.11/data/loaded_plugins /home/emqx-rel-2.3.11/data/loaded_plugins /home/emqx-rel-2.3.11/data/loaded_plugins /home/emqx-rel-2.3.11/data/loaded_plugins /home/emqx-rel-2.3.11/data/loaded_plugins
