When I am trying to use webpack in order to build my project and use it on AWS Lambda, I am getting a lot of warnings related to Critical dependency of ./node_modules/grpc.
This issue happening once I import {GoogleAdsApi} from 'google-ads-api';
As I can understand this is related to dynamic importing, I might be wrong.
As a result, the bundled file is huge (above 4MB) and when zipping it and using it on the Lambda I am getting the following error when the Lambda is triggered: "package.json does not exist at /package.json"
*Typescript
*Node ver 12.x
index.ts
import {GoogleAdsApi} from 'google-ads-api';
export const handler = async (event: any): Promise<any> => {
try {
console.log('Start', event);
// @ts-ignore
const api = new GoogleAdsApi({client_id: 'id', client_secret: 'secret', developer_token: 'dToken'});
return 'success';
} catch (e) {
console.log('Error', e);
throw e;
}
};
Error: package.json does not exist at /package.json,
