OCI runtime create failed: container_linux.go:380

I am trying to start a container from the given image below but I am getting the following error:

ERROR: for code_challenge_api Cannot start service api: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/app/entrypoint.sh": permission denied: unknown

ERROR: for api Cannot start service api: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/app/entrypoint.sh": permission denied: unknown
ERROR: Encountered errors while bringing up the project.make: *** [Makefile:3: api] Error 1

This is my docker-compose.yml file:

version: "3"services:  postgres:    image: postgres:13.2    container_name: code_postgres    environment:      - POSTGRES_USER=postgres      - POSTGRES_PASSWORD=postgres      - POSTGRES_DB=postgres    command: postgres -c 'max_connections=200'    ports:      - "5439:5432"    networks:      - localdockernetwork  api:    build:      context: ./api    container_name: code_api    volumes:        - ./api:/app        - ./api/models:/models        - ./api/tests:/tests    ports:      - "3001:3001"    networks:      - localdockernetwork    depends_on:      - postgres    tty: truenetworks:  localdockernetwork:

This is /app/entrypoint.sh file:

#!/bin/bashset -epushd models/migrationsalembic upgrade headpopdexec gunicorn -b 0.0.0.0:3001 --worker-class gevent app:app "$@"

How can I fix it?
