Hi, I’m working through N8N102 - Section 1 (API Integration Pipeline) and stuck on the final checkpoint. My FinalizePipeline node sends this payload to /course/n8n102/finalize: { “total_orders”: 50, “enterprise_count”: 12, “batch_size”: 10, “retry_enabled”: true } I get back a 422 error: “I…

Hi @muktern8n Welcome! The error names your counts, not your progress, so this is the payload rather than stale backend state. batch_size is the one value that doesn’t match Step 2.7, which uses 5. Set BatchPriorityOrders to a batch size of 5, re-run the whole workflow in one go, and finalize with b…

Adding to what Anshul said, since there is a thread with your exact error message (not the “Progress incompleted” one) where Jamie from the n8n team confirmed the batch size and posted a screenshot of the reference run: [صورة] : FinalizePipeline endpoint returning "Invalid f…

Hi @muktern8n I think the issue is the batch_size. For the final checkpoint, it should be 5, not 10. Your other values look right: { “total_orders”: 50, “enterprise_count”: 12, “batch_size”: 5, “retry_enabled”: true } I’d change BatchPriorityOrders to a batch size of 5, then run the complet…

Thanks Subham, batch_size: 5 was indeed the fix, and SendToPriorityQueue now runs successfully (all batches green, 12 items confirmed). However, FinalizePipeline is now back to a different error: “Progress incompleted. You have not completed all steps in this assessment.” This is confusing because …

@muktern8n A backend check isn’t needed, the flaw is in your flow. You listed orders quqed as 50, as proof step 1 sucseeded, however, in another thread, this was said the step 1 part wants only 10, so you need to disable pagnation. [صورة] N8N102 Section 1 Hands-on Exercise: Building an API Integr…

Thanks for the reply, but I think this might not be correct — the course document explicitly says in Step 2.1-2.2 that pagination should return 50 orders, and the confirmation code for that checkpoint literally contains “PAGED-ORDERS-QUEUE” in its name, which I received successfully. The rest of the…

@muktern8n لا يلزم فحص الواجهة الخلفية، العيب في سير العمل الخاص بك. لقد أدرجت الطلبات المصطفة بـ 50 كإثبات على نجاح الخطوة 1، لكن في موضوع آخر، قيل أن جزء الخطوة 1 يريد فقط 10، لذا تحتاج إلى تعطيل الترقيم.
