Deployment to AWS Elastic Beanstalk

[callumagmo]

Hi, I'm new to both medusajs and AWS.

Currently, I manage to deployed medusa starter template to AWS using EB CLI, but the server always returns the error 502 bad gateway.
This is what I got in the logs.

Mar 20 07:21:30 ip-172-31-45-26 web: > [email protected] start
Mar 20 07:21:30 ip-172-31-45-26 web: > medusa develop
Mar 20 07:21:30 ip-172-31-45-26 web: sh: /var/app/current/node_modules/.bin/medusa: Permission denied

I have tried the following solutions but seems no luck.

Then I have tried to deploy a simple express project and the server works fine.

Appreciate if anyone can help.
Do let me know if you need more information.
