Issue

I installed the completions as explained in the doc, and completions are working. But there is an error when triggering autocomplete with TAB key :

~/.config/fish/completions/poetry.fish (line 57):
complete -c poetry -f -n '__fish_poetry_e3d63c4129b80bf7_complete_no_subcommand' -a source show -d 'Show information about sources configured for the project.'
^
from sourcing file ~/.config/fish/completions/poetry.fish

I put the last error only, but the console print this error for almost every line of this file.
