Invoke AWS lambda from another lambda with Node 8.10

TypeScript resolver version for GraphQL:

async function getZipdata(cp: { [key: string]: string; }): Promise<any> {
 const payload: [key: string] = {
 “headers”: {
 “Accept”: “application/json”
 },
 “httpMethod”: “POST”,
 “body”: `{\”query\”:\”query { getZipdata(cp: \\\”${cp.cp}\\\”) {idmunicipio,municipio, asentamiento} } \” }`
 };
 const lambda = new AWS.Lambda({ region: ‘us-east-1’, apiVersion: ‘2015–03–31’ });
 const pullParams: any = {
 FunctionName: ‘zipcodes-service-dev-graphql’,
 Payload: JSON.stringify(payload),
 InvocationType: ‘RequestResponse’, // Synchronous call
 LogType: ‘None’
 };
 try {
 const result: any = await lambda.invoke(pullParams).promise();
 const parsed: any = JSON.parse(result.Payload);
 const body: any = JSON.parse(parsed.body);
 return body.data.getZipdata;
 } catch (error) {
 console.error(error);
 return false;
 }
}
