/docker-entrypoint.sh: line 50: exec: migrations: not found

I am not able to run the kong database after created a container for Postgres in the steps of kong installation steps mentioned in this page:

I am getting the following error on this command - docker run --rm --network=kong-ee-net
-e “KONG_DATABASE=postgres”
-e “KONG_PG_HOST=kong-ee-database”
-e “KONG_CASSANDRA_CONTACT_POINTS=kong-ee-database”
-e “KONG_LICENSE_DATA=$KONG_LICENSE_DATA”
-e “KONG_PASSWORD=xxxxxx”
kong-ee kong migrations

error:
/docker-entrypoint.sh: line 50: exec: migrations: not found

My system details:
OS : MacOS Catalina 10.15.6
Docker : v 19.03.12
Kong : v 2.1.0

Can you please look into this and let me know what is missing here?

Thanks,
