Hi @snake302,
Very odd. I just tried to replicate it and it worked. This is my flow:
Looking at your logs, it looks like it's working. I'd go into your secondary workflow and look at the job history to ensure you are sending the right data back via the response. Also, a mistake I've made a few times, is forgetting to hit deploy after making changes while working on connected workflows. So double check both workflows have the latest version deployed, and see what the response on the second one looks like in the logs. Feel free to post some screenshots if that doesn't solve it.
