This is a bit of a head-scratcher – and has been a source of pain for the past 3 hours. Here’s my code. const payloadBody = JSON.parse(gatewayEvent.body); console.log(payloadBody); console.log(gatewayEvent.body); console.log(payloadBody.paymentMethodId); console.log(payloadBody[‘paymentMethodId’]); console.log(Object.keys(payloadBody)); If I look at the CloudWatch logs for this (I am executing in Lambda), the line console.log(payloadBody) logs: { "customerId": "cus_REDACTED", "paymentMethodId": "pm_REDACTED", […]
