I keep getting an error as "Handle 'Pet dress' already in use. Please provide a new handle."

If a handle already exists, using it as a product identifier will cause an error. Shopify returns this error when a handle is already in use. To avoid this, we recommend not mapping the handle field. Without a specified handle, Shopify will not perform duplicate checks.
