I'm using the icingaweb2 nagvis module, which uses Leaflet to show a world map. Most things work, but when I click on the map, the following error is shown:

Javascript error occured: Uncaught TypeError: Cannot read property 'call' of undefined h t t p : / / icingaweb2.server/nagvis/frontend/nagvis-js/js/ExtLeaflet.js?v=1.9b12 (5)

I'm using version Leaflet 1.0.3+ed36a04 of Leaflet.

Inspecting the error in Chrome:

VM184 ExtLeaflet.js?v=1.9b12:5 Uncaught TypeError: Cannot read property 'call' of undefined

    at e.fire (VM184 ExtLeaflet.js?v=1.9b12:5)
    at e._fireDOMEvent (VM184 ExtLeaflet.js?v=1.9b12:6)
    at e._handleDOMEvent (VM184 ExtLeaflet.js?v=1.9b12:6)
    at HTMLDivElement.h (VM184 ExtLeaflet.js?v=1.9b12:6)

Can someone please help me fix the error?

  • Please use `leaflet-src.js` instead of `leaflet.js` to get more informative error stacks. – IvanSanchez Feb 14 '17 at 13:30
  • thank you `if (this._events) { var listeners = this._events[type]; if (listeners) { this._firingCount = (this._firingCount + 1) || 1; for (var i = 0, len = listeners.length; i < len; i++) { var l = listeners[i]; l.fn.call(l.ctx || this, event); //this is problem line } this._firingCount--; } }` – Shota Akhalaia Feb 15 '17 at 05:38
