What about server logs?

I think Bubble process the firstname correctly in the scheduling action but when it comes to triggering the backend workflow it doesn’t do that because of the type of things “Get Contact results” even though you only send text string.
You should be able to set it up as text, the list to run on should be list of texts so you would have to change it to “Hubspot connector - Get contact’s results firstname”. But I’m not 100% sure here
