The method you called is not defined

Error message

The method you called is not defined

What it means

Defined under shape.error.method, but Shape's invoke() dispatcher (shape.js:783-818) 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 (shape.js:725), not thrown.

Solutions

1. Use a documented shape method: 'flip up', 'flip down', 'flip left', 'flip right', 'set next side', 'refresh'.
2. Confirm the method exists for your installed version.

Example fix

// before
$('.shape').shape('flipp'); // typo -> silent no-op
// after
$('.shape').shape('flip up');

// Shape invoke() silently no-ops on unknown methods; validate first.
var shapeMethods = ['flip up','flip down','flip left','flip right','flip over','flip back','set next side','refresh','reset','is animating','destroy'];
function callShape($el, method, args){
  if (shapeMethods.indexOf(method) === -1) {
    throw new Error('Unknown shape method: ' + method);
  }
  return $el.shape(method, args);
}

When it happens

Trigger: $('.shape').shape('flipp') (typo) — dispatcher finds no matching key, returns undefined, no console output.

Common situations: Typo in method name, version drift.
