What does 'Uncaught TypeError' mean? #159

Hi, when using Dezoomify on the following page - http://www.bl.uk/magnificentmaps/map4.html - I get an 'Uncaught TypeError.' Does anyone know what that means or how I can fix it? Dezoomify works for other images on the same site (such as http://www.bl.uk/magnificentmaps/map3.html) so the error looks to be specific to this one page. I have pasted the full error text below. Thanks

Error

Uncaught TypeError: Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

I cannot reproduce the issue. The image is very large, so you have to follow the instructions in our FAQ to increase canvas memory, but then it just works.

Here is the resulting 500MB png: https://ufile.io/bz4y1 The full-resolution jpg: https://ufile.io/f4ewx
