We are trying to perform simple integrations, out of the box, with Drift and Hubspot and we keep getting the error:

CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY

I am not using triggers ... not using apex code ... and I have no idea what this issue means. Could it possibly be that we are trying to update records with a required field that isn't available from HubSpot/Drift???? Any help would be greately appreciated
