I'm having a problem using Shapeways' Etsy e-commerce integration on my products with a large number of "variants." Let's start with an item that works. Consider this item from my shop on Shapeways: https://www.shapeways.com/product/RYEPLHDHF/chaos-star-pendant Here's the corresponding Etsy listing: https://www.etsy.com/listing/233746869/chaos-star-pendant Since I offer the item in 11 materials, and with or without an engraved image, by Shapeways' count that's 22 variants. I had no problem using the Shapeways<->Etsy variant mapping page to link those variants to my Shapeways models (though it was tedious, but let's save the design of the page for some other time). Now consider this ring, one of several I have available on my shop. Here's the Shapeways listing: https://www.shapeways.com/product/P5KUVZ7E8/fairy-star-ring Here's the corresponding listing on Etsy, which I presently have to fulfill manually since I can't set up the integration: https://www.etsy.com/listing/233750081/fairy-star-ring I offer the ring in 3 materials, and 6 different ring sizes. That should come to 18 variants, less than the 22 variants of the other item. However, when I click on the EDIT button in the variant mapping page, there's a long pause followed by a page with the message "Error 504 - Gateway Timeout". This is the case for all the rings I sell on Shapeways and for which I'd like to set up Etsy integration. All of my other rings have more variations in both materials and available ring sizes than the above example, and have the same error message when I try to map their variants, but I'm starting with the simplest example. Is anyone else having this problem? Has anyone found a practical solution?
