I am running those services via the sh script:

docker-compose up -d
echo "****** Waiting for ${DELAY} seconds for containers to go up ******"
sleep $DELAY
docker exec mongo1 ./scripts/rs-init.sh
echo "****** Successfully started MongoDB and its dependencies ******"
The mentioned rs-init.sh is as follows:
#!/bin/bash
mongosh -u admin -p password --authenticationDatabase admin <<EOF
var config = {
"_id": "replicaSetConfig",
"version": 1,
"members": [
{
"_id": 1,

},
{

"priority": 2
},
{
"_id": 3,
"host": "mongo3:27017",
"priority": 1
}
]
};
//rs.initiate(config, { force: true });
rs.reconfig(config, {force: true});
rs.status();
EOF
When checking all the mongo-express instances logs in a Docker Desktop I can see following:
Could not connect to database using connectionString: mongodb://admin:password@mongo1:27017/?replicaSet=replicaSetConfig&authSource=admin"

I have tried many changes but without success. As I mentioned I do start container(s) via the mentioned script dbstart.sh.
Do not anyone know, if I am missing anything?
Thank you!
