I didn’t see the error that you referred to, however…
A couple of observations:
You have the repeater image connected to the Lightbox. That will cause a conflict with openLightbox when clicking on a Repeater item.
In both Lightboxes, you do a dataset.setFilter() in the pages onReady() function, but you need to put the code that does setFilter inside of a dataset.onReady() event handler . The reason is that even though the page is ready, that does not guarantee that the dataset is ready.
