configure .ebextentions file nginx file size limit increases AWS elastic beanstalk

Question

hey guys hope everyone is well. I created an ebxtentions file containing nginx.conf for my server because every time I update the file size from the ec2 server the updated settings don't stick because of the auto scaling group terminating and restarting my server.I was advised to create a .ebextentions folder with the config file in it which I did but it doesn't seem to work

please can someone review my config file and guide me to where I went wrong . thank you

  "/etc/nginx/nginx.conf": 
     mode: "six-digit octal value"
     owner: root
     group: root
