缺少symfony /config/maps.json'的本地副本

Question

I need to work on a site made with symfony, I downloaded directories, and files from live (working) site on my local environment, and when trying to access the site it gives me: The json file 'path-to/htdocs/config/maps.json' is missing I undesrtand I should change that somewhere as it should be;

/htdocs/SITE_NAME/config/maps.json

but where do I change that? If you think there are some other path changes to be made, please suggest them.

Thank you

EDIT to add sample of map.json
