Lambda handler parsing GC webhook payload

Node 18 Lambda failing to parse Genesys Cloud webhook events. The body field arrives as a string, but JSON.parse throws a SyntaxError on the second event in a batch. First event parses fine. Looks like the payload structure might be different than the docs suggest for batched events. Here’s the handler and the error.

export const handler = async (event: APIGatewayProxyEvent) => {
 try {
 const body = JSON.parse(event.body);
 console.log(body);
 } catch (e) {
 console.error(e);
 }
};

SyntaxError: Unexpected token o in JSON at position 1
