@kalip2 What is your output of this command: functions -q fish_right_prompt

[acomagu]

And could you provide your plugin list and config.fish?

The error probably occurs because your current setup and/or theme doesn't implement the right prompt.

I resolved this issue by explicitly setting the async functions to only use fish_prompt, overriding the default. You can do this by running the following command once in your shell, as shown in the README:

set -U async_prompt_functions fish_prompt

This command sets the universal variable async_prompt_functions to use only fish_prompt, which should prevent the error related to fish_right_prompt.

I also ran into this. If you're using starship, starship init fish | source might be in an if status is-interactive check. Moving it outside should fix it.

@LRNZ09 I think that doesn't match up with your explanation, because /usr/local/bin/starship init fish --print-full-init does have a fish_right_prompt function.

I think there might be a mix-up. I’m not using Starship or other themes for my Fish shell.

I know that Starship offers additional prompt configuration options, but my issue revolves around the standard Fish prompt and a few other plugins; this understanding led me to propose my solution.

@LRNZ09 I understand that not everyone experiencing this issue is using Starship. But when I tried it with Starship, I ran into this issue, even though Starship sets fish_right_prompt.

So maybe this issue isn't as simple as "your current setup and/or theme doesn't implement the right prompt".

I think https://www.reddit.com/r/fishshell/comments/vnal1x/comment/ie656h7/ is the explanation here?

fish-async-prompt starts a new fish process to do stuff. If you have defined your fish_right_prompt only when fish is interactive, that would break.

Also make sure you've updated fish-async-prompt recently because it had an issue that had symptoms like this.

[LRNZ09]

Probably the plugin will need some changes because, in your situation, having Starship loaded even when the shell is non-interactive seems unfit to me.

For instance, you may have it loaded with a fish shell script where a theme is not really necessary and might slow down the whole thing.
