After setting up products in Shopify and sync’ing to Commerce products in Roblox, when checking out via the shop.roblox.com in-app pop-over, an unknown error prevents progression to checkout (shipping/payment).
Repro
- Install Roblox app on Shopify
- Set up Shopify product
- Sync Shopify product to Roblox
- Create Commerce product based on sync’d Shopify product
- Wait for Commerce product to exit moderation queue (Pending → Approved)
- Mark the Commerce product ‘On Sale’
- In experience, use
CommerceService:PromptCommerceProductPurchase()to activate the shop.roblox.com in-app pop-over - Click “Buy now” (or alternatively, “Add to cart” and then “Continue to checkout” from the cart)
- See error that prevents proceeding
As far as I can tell, there are no logs indicating what’s going wrong. Since this is an embedded web page, this seems likely to be a bug in there, rather than something in the Roblox client itself. Since the embedded browser doesn’t expose developer tools, checking the actual requests/responses is a bit trickier for someone on the client side.
Roblox client on Windows 11:

Expected behavior
I expect that when clicking the “Buy now” would progress to the checkout process for the Commerce Shopify integration, or if there is a problem that is configuration-related to provide feedback indicating that.
