No available payment profile when pickup

Hi,

There is one more issue when we create pickup. Also not happening every time but this may / may not heppen, even with the same API token, same input.

{"message":"Failed to create Pickup","errors":["Something went wrong when requesting a pickup to Pickupp, please try later or contact Easyship Customer Service",[{"code":400,"content":"Pickupp First Mile label failed to generate - No available payment profile"}]],"pickup_fee":0.0,"available_balance":1000.0}

May I know what is the "payment profile" required and how can I set it up? or when is this payment profile required?
