I have inherited development of a website and Google translate was already implemented.
I have made mainly cosmetic changes to the site since taking it over but recently I have seen a lot (3000+) of broken links in Search console.
They follow the patten: Reffering page + string : domain/page/some_extra_string_that_does_not_exisst e.g.
/product/hbeab/lib/utils/*common*
/product/100ml-matt-black-glass-bottles-bamboo-atomisers-pack-of-140/*inffast*
/product-tag/5ml-bottle-dripper-insert/*zlib/deflate*
/product-tag/20ml-blue-glass-bottle-2-2/*lib/utils/common*
This code can't be seen in the source but only when inspecting source code (chrome) as I believe this is added after page load with javascript.
Google translate code:
<div id="google_translate_element"></div>
<script type="text/javascript">
function googleTranslateElementInit() {
new google.translate.TranslateElement({pageLanguage: 'en'}, 'google_translate_element');
}
</script>
<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
Code (I believe) is added by the above code:

Removing the google translate code removes the pako code but as search console can take days/weeks to re-index I cant tell if this is 100% the cause of the 404 links. However looking at the pako code I can see references to the erroneous link strings.
