I tried to upgrade node to last version in my instance, tried export node_options= --max-old-space-size=8192 in root of my project and in container, nothing helps. When i uninstal aws-sdk from package.json and deploy everything works. How to fix it.

Answer 1

The import method of service had to be changed. For example S3 instead

import { S3 } from 'aws-sdk';

you must use

import S3 = require("../../node_modules/aws-sdk/clients/s3");
