IE error when redirecting to DHL tracking site: The value of the property dcsMultiTrack is null or undefined, not a Function Object

I ran into a browser-specific error when trying to redirect to DHL tracking site from my app

I have this key in the AppSettings in my web.config file

<add key ="DHL" value="http://www.dhl.com/en/express/tracking.html?AWB={tracking_number}"

I also have a HyperLink Control like this

<asp:HyperLink id="hlink" runat="server" Target="_blank">
</asp:HyperLink>

Then I set the value in code behind:

hlink.NavigateUrl = String.Format(System.Configuration.ConfigurationManager.AppSettings["DHL"], myClass.TrackingNumber)

When the I click on the url and gets redirect to the site, when the page loads, a Webpage error window popped up with following message:

The value of the property dcsMultiTrack is null or undefined, not a Function Object

If I just ignore the message and hit "no" to the error window, the site will continue to load just fine. However, it is really ugly that everytime I get redirect to DHL the error shows up.

This only happens to IE, I tested with Edge and it was fine. Also,this function is not from my code, but from DHL's site. So I am not sure if there is anything I can do about it. Any suggestions will be appreciated.

I think this may have to do with the url am I using, is this URL out of date? what would be a good URL to redirect to DHL?

Solution

  • It turns out that this is the legacy DHL tracking site. For anyone who needs to use similar functionality, use the new URL instead:

    https://www.dhl.com/us-en/home/tracking/tracking-express.html?submit=1&amp;tracking-id={0}
