Invalid object data error for generated images

Somewhat similar to what we've seen before with #1196 where we were getting 500 errors, which turned out to be an image size thing, we're now getting "Invalid object data" errors in separated layers.

Occasionally the layers will just show up blank or empty, where text isn't being separated at all or is instead being put in the background. Most recently we're only getting these object data errors- previously only text layers weren't showing up, but now we're getting layer 2 (stafflines) not separating/throwing this error as well.

These images, when downloaded, are still viewable, and when used as inputs in pixel for correction do behave appropriately you just can't 'view' them in Rodan.
