what does this mean its happening when i try to preview a wardrobe item from my inventory

yeah, i've been having this issue for a while now. 😅 it seems like about half of CW previews and tree previews are broken for me. opening the broken image in a new tab gets this error.

i cleared my cache and it's improved, but there are still a lot of sporadic blue 'x's. safari 13.1.2

edit: also, the "CW shops" previews don't work. i'm sorry for the screencap taken by a potato.

this is post-cache clear lol
