Error message

invalid prompt type

What it means

bootbox.prompt only accepts input types for which it ships an HTML template (in this version: text, textarea, email, date, time, number, password, select, and later checkbox). The templates.inputs lookup happens before the input element is created, and an unknown inputType throws 'invalid prompt type'.

Solutions

1. Restrict inputType to the types your bundled bootbox version supports — check templates.inputs in the shipped uncompressed/bootbox.js for the authoritative list.
2. For unsupported types, use bootbox.dialog with custom HTML in the message, or fall back to a plain form.
3. Normalize the value: inputType: (type || 'text').toLowerCase() — guards against typos and missing defaults.

Example fix

// before
bootbox.prompt({ title: 'Pick a color', inputType: 'color', callback: fn });

// after
bootbox.prompt({ title: 'Favorite color', inputType: 'text', value: '#ff0000', callback: fn });

var SUPPORTED = ['text','textarea','email','date','time','number','password','select','checkbox'];
var type = (opts.inputType || 'text').toLowerCase();
if (SUPPORTED.indexOf(type) === -1) type = 'text';
opts.inputType = type;
bootbox.prompt(opts);

function isSupportedInputType(t) {
  return ['text','textarea','email','date','time','number','password','select','checkbox'].indexOf(t) !== -1;
}

When it happens

Trigger: bootbox.prompt({title: 'Pick', inputType: 'radio', callback: fn}); inputType: 'color', 'file', 'range', 'datetime-local', or leaving inputType undefined in a version where 'text' is not the default key present in templates.inputs.

Common situations: Expecting bootbox to mirror the full HTML5 input type list; version drift — upgrading bootbox changed the supported set (checkbox added in 4.3+, removed/renamed types across versions); typos in the type string ('Text', 'textarea ' with whitespace).
