 In the `while` loop, you loop over the array of products to sync them to Sanity. You use the `promiseAll` Medusa utility that loops over an array of promises and ensures that all transactions within these promises are rolled back in case an error occurs.

 You also wrap the `promiseAll` function within a try-catch block. In the catch block, you invoke and return `StepResponse.permanentFailure` which indicates that the step has failed but still invokes the rollback mechanism that you'll implement in a bit. The first parameter of `permanentFailure` is the error message, and the second is the data to use in the rollback mechanism.
 
+Finally, after the `while` loop and at the end of the step, add the following return statement:
+
+```ts title="src/workflows/sanity-sync-products/steps/sync.ts"
+return new StepResponse({ total }, upsertMap);
+```
+
 If no errors occur, the step returns an instance of `StepResponse`, which must be returned by any step. It accepts as a first parameter the data to return to the workflow that executed this step.
