System (please complete the following information):

Using fish, version 3.7.1 on MacOS 15.0.1.

Additional context

I installed fifc using fisher. Error started to occur today. I'm updating the module daily using fisher update and it was working fine earlier this week.

[eelcocramer]

When I install the version before the latest PR the error does not occur.

I.e. fisher install gazorby/fifc@1bc301453f674ed21fac4979c65a9a4cb7f2af61

[gazorby]

Does it occur once or every time you try to complete?

[eelcocramer]

Yes

Does it occur once or every time you try to complete?

For me, it happens every time I try to complete.
