Stuck in workflow 1 exercise in level 2 course

[DevDream]

Hi,
I’m attending the level two course, specifically I’m on the workflow 1 exercise:

Workflow 1 | n8n Docs

I managed to complete the steps 1 and 2, but I’m stuck on the nex steps, I don’t get how to do them:

3. Use the Merge node to merge data from Airtable and the Countries API by country name, represented as customerCountry in Airtable and name.common in the Countries API, respectively.

4. Use another Airtable node to update the fields region and subregion in Airtable with the data from the Countries API.

As for the step 3, I configured the node this way, but I don’t know if it’s correct:

As for the step 4, I don’t know at all what I have to do.

Some one could help me? Maybe someone who recently attended the course?
Also, why is there no solution to the exercise, as there was in course 1?

Thanks

Why did you choose to keep matches and only data from input 1?

[DevDream]

Because I don’t clearly understand how to do the exercise.
how would you do it?

Test other options there and try to comprehend the effects of your choices. Experimentation and observation is one of the methods of learning.
Your current choice simply bypasses data from input 1 without changing it, although when only conditions are met (coincidentally they all match since there are corresponding values in input 2 for every term in input 1). So the overall output content doesn’t meet the requirement, which is seen from the outputs tab.

How would I do it? I did. But here is the question for you: what is your objective in terms of learning? Passing the course is not a hard requirement to start using n8n. It is to help you climb the learning curve.

Experimentation is one of the skills that will help you to master other nodes here. Even if you end up with the desired result by means of trying every combination of parameters possible, you’re still making progress on your own.

Now, if I post a solution here, won’t it defeat the idea of learning on their own for multiple newcomers and spoil all the fun from learning things? Kinda copy-paste a solution and grab your diploma badge.

I’d rather help you to understand your decisions and guide you towards the solution than posting a ready-to-use suggestion. The choice is yours.

Hi Olek,
I see your point but I don’t have all the day to do this thing, after all this is a course, so why don’t put the solutions to the exercise?
Anyway, based on your suggestion, I made some changes, the wf now is like this:

For the merge node I made this change:

I added the final airtable node:

which gives me an error I don’t understand.

By the way, with these changes I managed to update the table, as requested by the exercise:

Could you please share the solution?

Thanks

I made my way through the course, there is no more need to answer this.
