When i made a autobrewer in singleplayer and it didnt work cuz the comparator didnt get powered so i checked without mods and it worked and when i watch the hopper while the potions come out i see them go thru so i started removing mods and adding them back if i had the same issue but when i removed fabric api the brewer worked again anything i can do to fix this?

Could you send a screenshot of a simple system that causes this issue?

If you are using fabric API 0.38.x or less, please update to the latest version, that should solve this issue.
Otherwise, could you post a forced crash report (F3+C) that will contain the list of available mods?
