The method you called is not defined.

Error message

The method you called is not defined.

What it means

This string lives under $.fn.sticky.settings.error.method, intended for unknown method-name invocations. In this codebase version Sticky's invoke() dispatcher (sticky.js:831-883) never calls module.error(error.method): when a string query resolves to nothing, 'found' stays undefined and the call silently returns undefined. So the message is dead config — you will not actually see it logged by Sticky. Like every module, module.error is a bound console.error (sticky.js:776), not a thrown exception, so try/catch is irrelevant.

Solutions

1. Spell the method name correctly and confirm it exists for Sticky in this version (e.g. 'refresh', 'scrollToTop').
2. Check the exact Semantic UI version's docs — method sets differ across releases.
3. Do not rely on try/catch to surface this; it is never thrown. If you need a hard failure, assert the return value is defined.

Example fix

// before
$('.sticky').sticky('refesh'); // typo -> silent no-op, returns undefined
// after
$('.sticky').sticky('refresh'); // valid method

// Sticky's invoke() returns undefined for unknown methods (never throws).
// Validate against the known method list before calling.
var stickyMethods = ['refresh','observeChanges','set offset','set container','is sticky','bound','unbound','bind events','unbind events','scrollToTop','destroy'];
function callSticky($el, method, args){
  if (stickyMethods.indexOf(method) === -1 && typeof $el.sticky('module')[method] === 'undefined') {
    throw new Error('Unknown sticky method: ' + method);
  }
  return $el.sticky(method, args);
}

When it happens

Trigger: $('.sticky').sticky('nonexistentMethod') — the dispatcher (sticky.js:843-865) walks camelCase/dotted segments against the module instance, finds no match, sets found=undefined, and returns undefined with no console output.

Common situations: Typo in a method name, using a method from a different Semantic UI version, copy-pasting an API call from another module (e.g. dropdown) into sticky.
