Cannot read property "checkImageForCriticality" of Undefined

I get this error when refreshing.

Thanks in advance for any help.

That sounds a bit like https://github.com/pagespeed/mod_pagespeed/issues/1281
Does the page that you refresh depend on JavaScript for loading html?

Yes, the page i’m loading does depend on javascript
I saw that issue but was unsure what he meant to do
Is he saying to add
location /xhr {
ModPagespeedDisableFilters prioritize_critical_css;
}
to my server block?
I’m not exactly sure what this has to do with CSS

[Danny Michel]

I mean 

location /xhr {

       pagespeed DisableFilters prioritize_critical_css;

If you have javascript running on your page which loads a html fragment from, say, /ajaxhtmlfragment, you should probably disable the prioritize_critical_css filter for /ajaxhtmlfragment. Doing so would allow you to avoid getting the js error that you are seeing.
