Line 873 produces the following error when I run gh fzf i and then alt-o. This happens on MacOS using Tabby terminal and zsh.

➜  my_project git:(main) gh fzf i

Thanks for the bug report! I can't reproduce on Ubuntu and Bash, but I'll try to investigate.

Does the error occur before the prompt is displayed or after you enter a branch name and press enter? Also, which version of fzf do you have installed?

[benelan]

It looks like fzf versions prior to 0.53.0 required manual /dev/tty redirection when interactive programs are used in execute actions. If your fzf version is less than 0.53.0, can you try the fix on benelan/38-read-error and let me know if it resolves your error? Thanks!

@benelan that worked - thank you! For context, the error was after pressing option-o (MacOS).

[rorybyrne]

Also my fzf is at 0.54.3.

[benelan]

Also my fzf is at 0.54.3.

Interesting, it must be something related to zsh or Mac then. I fixed all of the issues related to read, but there may be other tty problems that I don't reproduce on my end either. If you find one, please log another issue and I'll get it fixed. Thanks again for the report!
