Hey there,
I was just poking around your prospects n8n workflow and I think you're using a deprecated version of the apify actor node. I'm getting this even after installing it and it doesn't want to work.
Looking at the json it seems you use:
```
"type": "@apify/n8n-nodes-apify.apify",
```
But the working one (in my case) is:
```
"type": "@apify/n8n-nodes-apify.apifyTool",
```
Hope this helps!
