How can I fix [entrypoint.sh: not found] in Docker?

I have a Django project file and Docker in Ubuntu server.And when I build docker image, it creates well.But when I up this image, 'python: 1: ./AA/entrypoint.sh: not found' error occurred.

My Dockerfile is

FROM python:3.10.11WORKDIR /usr/src/app/serverENV PYTHONDONTWRITEBYTECODE 1ENV PYTHONUNBUFFERED 1RUN apt-get -y update \&& apt-get install -y postgresql postgresql-contrib \                libpq-dev \                gcc \                python3-dev \                musl-devRUN pip install --upgrade pipCOPY ./requirements.txt .RUN pip install -r requirements.txtCOPY . .ENTRYPOINT ["sh", "-c", "./AA/entrypoint.sh"]

My entrypoint.sh is

#!/bin/shif [ "$DATABASE" = "postgres" ]then        echo "Wating for postgres..."        while ! nc -z $DB_HOST $DB_PORT; do                sleep 0.1        done        echo "POSTGRESQL started"fipython manage.py flush --no-inputpython manage.py migrateexec "$@"

And the structure of files is...

In /usr/src/app/server/AA/,   -> Django projects by git clone   -> Dockerfile   -> docker-compose.yml   -> entrypoint.sh

I tried these codes in Dockerfile, but all have same error.

ENTRYPOINT ["entrypoint.sh"]ENTRYPOINT ["sh", "-c", "./entrypoint.sh"]ENTRYPOINT ["sh", "-c", "./AA/entrypoint.sh"]ENTRYPOINT ["sh", "-c", "/usr/src/app/server/AA/entrypoint.sh"]
