SnipeIt using Docker Compose

Question

the URL section in the image attached says -

" Uh oh! Snipe-IT thinks your URL is http://127.0.0.1:8082, but your real URL is http://app_url_placeholder/setup Please update your APP_URL settings in your .env file "

the .yml file is - this is the .yml file in docker-compose

I am unable to understand what is going wrong with snipe-it - that it is not working on the local host and says- "Uh oh! Snipe-IT thinks your URL is http://127.0.0.1:8082, but your real URL is http://app_url_placeholder/setup Please update your APP_URL settings in your .env file "

I have been trying to find the solution since hours - please can I get some help on this.

Reference for the .yml file - https://github.com/linuxserver/docker-snipe-it

The solution to the above problem is - just small modification to the .yml file

the Correct .yml file for reference
