Hi guys,

We've recently set up Javascript tracking, but raygun seems to hit an error when on our basket page (eCommerce application)

The script is being loaded like so:

<script  type="text/javascript" src="/js/raygun.min.js"></script>
<script type="text/javascript">
    Raygun.init('APIKEYHERE');
</script>

And the error we see in chrome console (using the non-minified raygun for clarity) is as follows:

Chrome console

Thanks,

Sam

Hi,

Could you please provide a list of any other external libraries or scripts which may be adding onerror handlers, if any? Also it may be useful if you load your page then call window.onerror in the console, then paste the output here.

window.onerror returns:

function (n,e,t,o,a){var u=null;if(a)u=r.computeStackTrace(a);else if(s)r.computeStackTrace.augmentStackTraceWithInitialElement(s,e,t,n),u=s,s=null,l=null;else{var c={url:e,line:t,column:o};c.func=r.computeStackTrace.guessFunctionName(c.url,c.line),c.context=r.computeStackTrace.gatherContext(c.url,c.line),u={mode:"onerror",message:n,url:document.location.href,stack:[c],useragent:navigator.userAgent}}return i(u,"from window.onerror"),f?f.apply(this,arguments):!1}

The page is using:

jQuery UI 1.7.2 jQuery 1.10.1 Some custom checkout js

Nothing that should be adding any onerror handlers that I'm aware of though.

Thanks,

Sam

Hm, that looks correct - I have created a branch with a candidate fix for this condition, if you could grab it from https://raw.githubusercontent.com/MindscapeHQ/raygun4js/undefined-function-guard/dist/raygun.js and let me know if it fixes the problem. If it does I will get it merged+deployed as a new version.
