Drip Email - problems creating/updating subscribers

Hi - very new Make user but have consistent problems integrating Drip email platform with any information that comes in e.g. tagging and updating as a purchaser in thrivecart.

Is there a specific method makes Drip and Make play better? I don’t want to go back to Z4pier but that always works…

The specific errors are commonly bundle errors and I’ve tried using direct links, routers, text parsers etc.
