How can I use usethis to increase version of my R package on google cloud platform?

I’m trying to increase the version of my package an R session on google cloud platform. I think I must be missing something because I thought when which was set that the code should be able to run without further user input.

rlang::is_interactive() returns FALSE as I’d expect.

usethis::use_version(which = "minor")
✔ Setting active project to '/home/jupyter/x/y'

Error: User input required, but session is not interactive.
Query: There are uncommitted changes and you're about to bump version
Do you want to proceed anyway?
Traceback:

1. usethis::use_version("minor")
2. challenge_uncommitted_changes(msg = "There are uncommitted changes and you're about to bump version")
3. ui_yeah("{msg}nDo you want to proceed anyway?")
4. ui_stop(c("User input required, but session is not interactive.", 
 .     "Query: {x}"))

Here’s the function code: https://github.com/r-lib/usethis/blob/master/R/version.R

function (which = NULL) 
{
    if (is.null(which) && !is_interactive()) {
        return(invisible(FALSE))
    }
    check_is_package("use_version()")
    challenge_uncommitted_changes(msg = "There are uncommitted changes and you're about to bump version")
    new_ver <- choose_version("What should the new version be?", 
        which)
    if (is.null(new_ver)) {
        return(invisible(FALSE))
    }
    use_description_field("Version", new_ver, overwrite = TRUE)
    if (names(new_ver) == "dev") {
        use_news_heading("(development version)")
    }
    else {
        use_news_heading(new_ver)
    }
    use_c_version(new_ver)
    git_ask_commit("Increment version number", untracked = TRUE, 
        paths = c("DESCRIPTION", "NEWS.md", path("src", "version.c")))
    invisible(TRUE)
}

Is this a possible bug in choose_version()?
