Hi @Zipline 

Good question.

We would need to see how your Zap step is configured with screenshots.

Thanks @Troy Tessalone, here’s a screenshot above. I’ve made sure that Jenn is a member of the basecamp project as well.

@Zipline 

Can you post a screenshot of the related Person in Basecamp as proof?

Perhaps try searching by email address as that’s a unique value.

Ok I realize what the issue is. The emails in Basecamp are under a different alias than what we have in SFDC, so it’s not able to do a proper look up, thus the error message. I will reach out to our internal support for help on this. Thanks troy!

Thanks for letting us know @Zipline! Really appreciate you taking the time to circling back here to share your findings with the rest of the Community.
