Using templates with Custom Hubspot App

Hi all,

I am trying to connect Google sheets to my Hubspot app in order to import historic emails. I have set up the app and everything seems to be working. However, somehow my template is pasted twice when sending the activity to Hubspot. I have tried everything to find the problem but so far no luck (as well as when approaching the Hubspot & Make support desk.

Anyone here who has experience with using the timeline events and can help me out?

Many thanks! :slight_smile:
Best
