Bitnami Discourse 3.3.2 update error

Problem:

Do you get this error trying to update your Bitnami Discourse installation?

NameError: uninitialized constant ChatMessageSerializer::BasicUserWithStatusSerializer (NameError)

has_one :user, serializer: BasicUserWithStatusSerializer, embed: :objects
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Did you mean? BasicUserSerializer
/opt/bitnami/discourse/plugins/chat/app/serializers/chat_message_serializer.rb

Solution:

You can fix this error and finalize the upgrade process by removing your discourse/plugins/chat folder.

I had this issue for multiple discourse versions starting from Discourse 3.0.6
