I have the issue is on my end for my particular Assessment ID or session. When I was working on Section 2 earlier, I accidentally deleted the credentials/setup for that section before moving here. I suspect this might have broken the sync or invalidated my Assessment ID on the backend, causing the s…

I see, yeah, maybe the n8n team needs to update that instruction. For now, if your credentials already have x-assessment-id, which is great and correct. To fix this, you will need to click the Send Headers to toggle it on and add X-API-KEY with value j[vKYdY68H(:WFb (this from the course). What thi…

Well your assesment ID isnt attached to your instance, its to your academy account, can you elaborate more?

To be more precise, the “Authorization data is wrong” error actually started appearing in Section 3 BEFORE I deleted anything. Here is the exact timeline: 1. Section 2 was working perfectly. 2. When I moved to Section 3 (AI Agent), I tried using the header credentials from Section 2, but it immed…

Hi @Ageng_Prayogi , Sorry, it’s a bit confusing for me, as I can’t find the sections you mention in the course N8N101: Essential: Your First Workflow (which sub-category you posted in). I find this more likely to be the course QS101: n8n Quickstart. Please help me confirm which course you mentioned…

Hi! Yes, my bad, you are totally right. It is indeed the **QS101: n8n Quickstart** course. Thank you for the tip about checking where the Forbidden error comes from. I have taken screenshots of my HTTP nodes for both sections as requested. 1. **Section 2 Node Setup & Error:** [Attach GetOrderData(Se…

Cool @Ageng_Prayogi , I’ve also just found where the problem is. Please check my post and ensure the HTTP node has both x-assessment-id and X-API-KEY. Cheer [image] Assessment ID not working for Customer service agent module Hi @Chanpreet , For the agent’s HTTP request node, it requires both t…

Hi, thank you for the response! I have checked the course instructions again, and it explicitly asks to use x-assessment-id as the header name [as shown in Screenshot 1]. I have double-checked my credentials and they perfectly match this requirement. However, when running the full execution via th…

Hi! You nailed it. That was exactly the missing piece! It turns out the endpoint required both headers to be present. Interestingly, on my first attempt to fix it, I accidentally flipped them: I put the X-API-KEY inside the Generic Header Auth credentials, and toggled “Send Headers” to manually pas…

Haha, yeah. You must be the one who nailed it. You’ve put a lot of effort into flipping back and forth between Sections 2 and 3 to fix this. Your detailed steps are why I could trace how things went wrong between the two sections. Enjoy your hacking weekend, Ageng!

We do have a step that says Ensure you are also sending your X-Assessment-ID headers :slight_smile:

Hi @jamiemadden_n8n Great!. But I’ve checked, and that phrase is only in the N8N103 , and not in the QS101’s Section 3 , where people recently met this issue.
