Hi, In one of my projects, I suddenly got a strange error when trying to search with a different ranker.
To reproduce the problem, I created an empty Rails (5.1.4) project with only one model (city): class CreateCities < ActiveRecord::Migration[5.1] def change create_table :cities do |t| t.string :names t.timestamps end end end and an index: ThinkingSphinx::Index.define :city, :with => :active_record do # fields indexes names end After I have generated the Sphinx config file and I indexed the records I am able to search e.g. City.searc('amsterdam') But as soon as I add a ranking mode like: City.search('amsterdam', ranker: :bm25) I get the warning below: Could not log "warn.thinking_sphinx" event. NoMethodError: undefined method `payload' for " \e[1m\e[32mSphinx\e[0m ":String

I cannot find which change has triggered this strange warning. Does anyone have the same issue and maybe a hint how to solve it?
