Critical error when <img srcset="">

[ryangorley]

I'm not entirely sure why some of my images acquired an empty srcset="", but it is crashing the build due to HTMLProcessor.php line 635 expecting a string. I was able to work around this by getting rid of that blank attribute, but it is seems it could plausibly happen when someone else is using a site layout tool like I was which stuck those in there for some unknown reason. Here is the full log w/ stack trace:

By chance is there any Lazy Load Plugin active?

Nope. I'm pretty sure the Oxygen builder was the source of the blank srcset.
