Mobile Payment SDK - invalidPaymentParameters

Questions

Hello!

When attempting to process a cash payment in sandbox mode i’m getting invalidPaymentParameters error

This is the payload passed into the startPayment method

{“amountMoney”: {“amount”: 1819, “currencyCode”: “CAD”}, “locationId”: “L8F6YYEYVZMTQ”, “note”: “Order #298955D0”, “paymentAttemptId”: “141ab0bf-1a51-4397-ad5e-dc67c1866468”, “processingMode”: 0, “referenceId”: “298955d0-8471-4600-b090-ec1b4bb29313”, “teamMemberId”: “TMdYSEd47R6IF2I-”}

This is the error i’m getting: “The PaymentParameters provided were invalid. Check the request details and try the payment again.”

What doesn’t it like? I’m using a sandbox applicationId and teamMemberId and locationIdand also the the accessToken from the sandbox test account oAuth section. Which is sent to the app to authenticate the mobile SDK
