read email input failed: %w

Error message

read email input failed: %w

What it means

ResetPassword wraps a failure from reading the user's email from stdin via bufio.Reader.ReadString('\n') when opts.Email was empty. This happens in interactive prompts; typically it means stdin was closed or an I/O error occurred.

Solutions

1. Pass the email explicitly via options (opts.Email) instead of relying on stdin.
2. Run interactively with a real TTY (e.g. docker run -it).
3. If piping input, ensure the email line is present on stdin.

Example fix

// before
_ = cli.ResetPassword(ctx, dataDir, &cli.ResetPasswordOptions{})
// after
_ = cli.ResetPassword(ctx, dataDir, &cli.ResetPasswordOptions{Email: "admin@example.com"})

if opts.Email == "" && term.IsTerminal(int(os.Stdin.Fd())) == false {
    return fmt.Errorf("non-interactive session: pass --email")
}

if err := cli.ResetPassword(ctx, dataDir, &ResetPasswordOptions{}); err != nil {
    if strings.Contains(err.Error(), "read email input failed") {
        log.Fatalf("stdin unavailable; pass --email explicitly: %v", err)
    }
}

When it happens

Trigger: ResetPassword invoked without --email (or with empty opts.Email) in a non-interactive context — piped input exhausted, stdin closed, no TTY.

Common situations: Running the CLI in CI/scripts without passing the email flag, docker run without -i, output piped so stdin is /dev/null.
