Shopify CLI - Shopify node serve is not working for 1 year old project

Question

I am trying to refactor my old shopify project but, when I run command, "shopify node serve" It gives me the following error.

"This command can only be run within node projects."

But, It is a node project. It is a next.js shopify application.

Below is my package.json file.

}

My node version is: 14.6.0 Shopify version: 2.6.5

I am not sure what is the problem, Only shopify node commands related to starting the server, are not working. All other shopify commands are working.
