shopify-api-ruby: Invisible error when updating large number of products

Hello,

First, thanks for the great work with the gem. I unfortunately have a weird issue:

• I have a local DB of around 7000 products. They need daily modifications
• Once a day, I iterate on my products and send the modifications to Shopify. Of course, I respect the Shopify API limit (and rescue to relaunch when I send too many requests)
• I never get any error but unfortunately, only around 5000 products really get updated in Shopify. I don’t get what happens to the other ones…

My code (with only the relevant parts):

saved = @shopify_product.update_attributes(shopify_hash.attributes)
Rails.logger.info("ShopifyProduct #{@shopify_product.id} updated: #{@shopify_product.to_json}") if saved

But in the product below for example, I get the logs below but the product is not updated in Shopify (cf picture). See the tags for example.

Do you have any idea of the reason? I really don’t have a clue as I don’t receive any error… Thanks so much, Damien
