The method you called is not defined.

Error message

The method you called is not defined.

What it means

Defined under modal.error.method, but Modal's invoke() dispatcher (modal.js:877-915) never calls module.error(error.method): an unknown method name leaves found undefined and returns silently. The string is dead config in this version. module.error is a bound console.error (modal.js:822), not a thrown exception.

Solutions

1. Use a documented modal method: 'show', 'hide', 'toggle', 'refresh', 'set active', etc.
2. Confirm the method exists for your installed version.
3. If you need a hard failure, check the return value rather than expecting a throw.

Example fix

// before
$('.ui.modal').modal('showw'); // typo -> silent no-op
// after
$('.ui.modal').modal('show');

// Modal invoke() silently no-ops on unknown methods; validate first.
var modalMethods = ['show','hide','toggle','refresh','set active','set dimmer variation','can fit','is active','is animating','set observations','attach events','show dimmer','hide dimmer','destroy'];
function callModal($el, method, args){
  if (modalMethods.indexOf(method) === -1) {
    throw new Error('Unknown modal method: ' + method);
  }
  return $el.modal(method, args);
}

When it happens

Trigger: $('.ui.modal').modal('showw') (typo) — dispatcher finds no matching key on the module instance, returns undefined, no console output.

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