New Warning: DraftOrderMarketRegionCountryCodeNotSupportedWarning
Shopify has introduced a new warning type for draft orders: DraftOrderMarketRegionCountryCodeNotSupportedWarning. This warning appears when you set the deprecated marketRegionCountryCode field on a draft order in stores using Shopify Markets (community.shopify.dev).
What’s Changing
-
The
marketRegionCountryCodefield is no longer supported on stores that use Shopify Markets. -
When a draft order is created, calculated, or updated with this field included, Shopify now returns a warning of this new type (shopify.dev).
-
Draft orders still work, but the presence of the field may indicate outdated logic or potential future compatibility issues.
Why This Matters
-
Remove Deprecated Fields: The warning signals that your code is using an outdated field, which could break in a future release.
-
Prevent Silent Errors: Catching this early avoids downstream issues in your automation or ERP sync processes.
-
Stay Market-Compatible: For stores selling across multiple regions with Shopify Markets, clean API use ensures consistent behavior across markets.
How to Handle It
-
Audit your draft-order logic
Look for any instance wheremarketRegionCountryCodeis set or passed during draft order creation or updates. -
Remove or replace the field
Remove it from your payload. Draft orders will continue to work without it. -
Monitor warnings
Adjust your logging or error reporting so this warning triggers an alert letting you catch similar issues proactively.
Takeaway
Shopify is guiding developers to modernize their custom integrations. While this warning doesn’t break functionality today, it helps you stay ahead of deprecated fields and ensure your code remains clean and reliable. If you're building tools or automations around draft orders, it’s worth updating now.
