Unexpected token import for nodejs on GAE Flex

I deployed a nodejs app on appengine flexible today. But the deployed server won't start with the following error in the logs. I'm confused why my import statement is being marked as errors. Please help! Thanks in advance.

A  /app/src/server/index.js:2
 
A  import gqlServer from './myServer';
 
A  SyntaxError: Unexpected token import

The import keyword is only supported in the newest Node v8.5.0 I believe, and even then, behind a flag. You'll need to set your engines field in package.json to >=8.5.0 and your start script to node --experimental-modules src/server/index.js. And, I believe your index.js actually needs to be index.mjs.
