Invalid input

Error message

Invalid input

What it means

When resume runs with no ID and a terminal is available, Codewhale prints a numbered session list and reads one line from stdin. The trimmed line must parse as usize; non-numeric input like 'abc' or '1a' fails with 'Invalid input'. Empty input cancels earlier with 'No session selected.'.

Solutions

1. Enter the 1-based number shown next to the session, or press Enter on an empty line to cancel
2. In scripts, avoid the picker entirely: pass codewhale resume <SESSION_ID>
3. When pasting, paste digits only
4. Re-run and choose again after a typo

let input = read_line_trimmed();
if !input.is_empty() && input.parse::<usize>().is_err() {
    eprintln!("enter the 1-based list number, or press Enter to cancel");
}

fn is_valid_selection_input(input: &str) -> bool {
    let t = input.trim();
    t.is_empty() || t.parse::<usize>().is_ok()
}

When it happens

Trigger: Typing letters, punctuation, or mixed text at the picker prompt; piping unexpected text into stdin from a script; terminals injecting escape sequences on paste.

Common situations: Muscle memory types a session name or ID prefix instead of its list number; automation feeds non-numeric stdin to an interactive command.
