Fix Shopify CSV invalid fulfillment service values
Imports can fail or behave unexpectedly when fulfillment service values are malformed or inconsistent with your store settings.
Why Shopify throws this error
Fulfillment service fields are validated against known service options. Unknown values or deprecated labels can fail mapping.
Common causes
- - Old service names persisted after app uninstall.
- - Manual typos in fulfillment service cells.
- - Cross-store CSV copied with services that do not exist in target store.
- - Mixed service naming conventions in one file.
