Docker build no No such file or directory

From the directory I am trying to run the command

sudo docker-compose -f project/docker/docker-compose.yml up

This is the error I get

    ubuntu@ip-172-31-90-166:~/tp3-securite-applicative$ sudo docker-compose -f project/docker/docker-compose.yml up
    Recreating docker_api-service-track-1_1 ... done

    api-service-track-1_1  | //project/
    api-service-track-1_1  | running the following python program

    api-service-track-1_1  | python3: can't open file '//./project/codeAPI/front.py': [Errno 2] No such file or directory

This is my Dockerfile

FROM python:3
ADD ./run.sh /
ADD ./requirements.txt /
RUN pip3 install -r ./requirements.txt
CMD ["./run.sh", "./project/codeAPI/API.py", "./project/codeAPI/front.py"]

This is my docker-compose.yml

version: '3'

services:
  api-service-track-1:
    build:
      context: ../../
      dockerfile: ./project/docker/Dockerfile
    image: img_track1
    volumes:
      - ./:/mnt/app
    ports:
      - 5551:5551
    tty: true

I define my python path in my run.sh

#!/bin/bash

export PYTHONPATH=$PWD/project/
echo python path is:
echo $PYTHONPATH

echo running the following python program
echo $@
python3 "$1"
python3 "$2"

requirements.txt contains a bunch of imports.

I tried multiple ways to adapt my python path by modifying my run.sh and my Dockerfile but I am unable to find my front.py and API.py. Do I not understand the concept of path or am missing something obvious?

edit 1 after Saikiran Rudra correction:

ubuntu@ip-172-31-90-166:~/tp3-securite-applicative$ sudo docker-compose -f project/docker/docker-compose.yml up

>Solution :

I faced similar problem try this it worked for me

In docker-compose.yml in volumes section add this lines

volumes:
      - ./:/mnt/app
      - /project/codeAPI/API.py
      - /project/codeAPI/front.py
