Please provide some assistance. 

I have been trying to integrate Zoho CRM with Hubspot (using Zapier) so that when I create a lead or contact in Zoho CRM, it results in a new contact being created in HubSpot. Unfortunately I have been unsuccessful. Every time I try and test this in the Hubspot Zapier interface, I am given this error " No contact with email 'test@gmail.com' was found. Unable to add unknown contact to list." I believe that the error may be coming from the Zoho CRM side because I am able to successfully create new contacts in Hubspot that are saved in Zoho CRM as contacts. 

Please advice.
