I installed heroku cli via snap (sudo snap install heroku --classic), but the autocomplete does not work throws an error: _heroku:2: HEROKU_AC_ANALYTICS_DIR: parameter not set, never encountered this before, who knows what could be the problem?
i`m using the zsh command shell
Try this solution: https://devcenter.heroku.com/articles/heroku-cli-autocomplete
heroku update
heroku autocomplete
Worked for me.
UPD: Run the following after commands above (heroku asks to do this after running them anyways):
printf "$(heroku autocomplete:script zsh)" >> ~/.zshrc; source ~/.zshrc
