The method you called is not defined.

Error message

The method you called is not defined.

What it means

Emitted by Nag's invoke() dispatcher (nag.js:397) when a string method name does not resolve to any property on the nag module instance. Unlike the dead-config modules, Nag actually logs this via module.error (nag.js:310), a bound console.error gated by settings.silent. It is not a thrown exception.

Solutions

1. Use a documented nag method: 'show', 'hide', 'clear', 'dismiss', 'storage', etc.
2. Confirm the method exists for your installed version.
3. Set silent:true to suppress the console message once you have confirmed it is benign.

Example fix

// before
$('.nag').nag('clearr'); // typo -> console.error
// after
$('.nag').nag('clear');

// Validate against nag's method list before invoking.
var nagMethods = ['show','hide','clear','dismiss','storage','destroy'];
function callNag($el, method, args){
  if (nagMethods.indexOf(method) === -1) {
    throw new Error('Unknown nag method: ' + method);
  }
  return $el.nag(method, args);
}

When it happens

Trigger: $('.nag').nag('clearr') (typo) — the dispatcher's lookup (nag.js ~390-398) finds no matching key and calls module.error(error.method, query).

Common situations: Typo in a method name, using an API from a different version.
