Unable to deploy the starter on aws

[Cally99]

Hi, I'm having issues setting this starter up on aws.
I've created and EC2 instance with Amazon 2
Installed, git, nvm, npm, yarn & node on the instance.
Then yarn install.

Usually on local I would run yarn develop on the main directory that has both frontend and backend.

Unfortunately strapi isn't recognising the command.
With npm install strapi and trying again same issue.

I think there's an issue with yarn which this project is set up on ec2 Amazon 2 servers.
Nvm use 14.19.1 is my version.

Does anyone know what compat issues there are for deploying on aws?

Has anyone and updated script to add to the repo?
Or faced same issue?

Thanks
