"Incorrect function" error in Windows Git Bash terminal

[DouglasLivingstone]

Describe the bug

When running commands that require interactive input in the Windows Git Bash terminal (installed using the Windows Git installer), there is an error:

$ gh pr create
Creating pull request for [...] into master in [...]
? Title could not collect title and/or body: could not prompt: Incorrect function.

Versions:

$ git --version
git version 2.25.0.windows.1

$ gh --version
gh version 0.5.4 (2020-02-04)
https://github.com/cli/cli/releases/tag/v0.5.4

Steps to reproduce the behavior

1. Install Git and GitHub CLI on Windows
2. Open Git Bash, and cd into a repo
3. Run gh pr create

Expected vs actual behavior

Expectation is the interactive UI to create a PR, instead there is an error message:

? Title could not collect title and/or body: could not prompt: Incorrect function.

Thank you for reporting! This sounds like AlecAivazis/survey#148

Is there a workaround that can be used until the upstream issue is resolved?

Have you tried to use cmd instead of bash?

Yes, the error hasn't displayed if I use cmd

Seems to be a MinTTY issue again...

All those people who are having this issue... While installing git, what option did you choose? (See pic)

@mislav ?

[mislav]

We are aware of the issue, but we don't know what part of MinTTY is incompatible with the Survey library (or vice versa).

A temporary workaround might be to disable prompting gh config set prompt disabled and pass all necessary information via flags instead.

or another workaround is to use Git Bash in Windows Terminal

@mislav I suggest closing this as an external bug (if you close external bugs)
