I’ve managed to do what I wanted following the post in [Error when logging in on Forest with admin backend deployed on AWS in lambda function - #16 by Cyril\_Limam](https://community.forestadmin.com/t/error-when-logging-in-on-forest-with-admin-backend-deployed-on-aws-in-lambda-function/465/16)

I’ve updated to app.js file to return an async createApp function. And the server.js to use “const app = await createApp();”

It works now 👌
