bash_execute_unix_command: cannot find keymap for command

[tynes]

When I press \C-k on my keyboard, I get the error:

-bash: bash_execute_unix_command: cannot find keymap for command

I am running:

GNU bash, version 4.4.19(1)-release (x86_64-apple-darwin17.3.0)

I installed this version of bash using homebrew I am running this in iTerm2 and don't have any special iTerm settings involving keymaps Any idea what could be causing this problem?
