Where is the error in this workflow?

Hello fellow N8N users

I’m running into an error with a transfer of data between my AI agent and “execute an another workflow” All I need it is for the data to transfer over and have the next workflow start seamlessly. I’ve attached the workflow code in JSON for further review. This is a workflow for a LinkedIn lead scraper.

Thanks in advance!
