Docker-compose: OCI runtime create failed, no such file or directory for entrypoint.sh

I am struggling to run docker-compose when using an entrypoint.sh file. I am receiving this error even though I have run chmod +x on the file. Any idea what I am doing wrong?

ERROR: for airflow_webserver_1  Cannot start service webserver: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"./airflow/scripts/entrypoint.sh\": stat ./airflow/scripts/entrypoint.sh: no such file or directory": unknown
