Hi guys, I'm currently trying to get the tap-paypal (https://github.com/Yoast/singer-tap-paypal) working. After setting it up in the meltano.yml with all necessary configuration parameters I tried to invoke the tap for testing. Unfortunately I get the following error-message:

tap-paypal             | INFO Syncing stream: paypal_transactions

tap-paypal             | CRITICAL paypal_transactions() argument after ** must be a mapping, not NoneType

tap-paypal             | Traceback (most recent call last):

The tap seems to need a state file and I'm not sure how Meltano handles that. Maybe some of you can help me 🙂
