./generate-peer.sh is broken?

[kilpio]

./generate-peer.sh exits with
bash: crypto-config/fabric-ca-server-config-org1.yaml: Is a directory

Seems that
envSubst "templates/fabric-ca-server-template.yaml" "crypto-config/fabric-ca-server-config-$ORG.yaml" "export LDAP_BASE_DN=${LDAP_BASE_DN}"
expects the crypto-config/fabric-ca-server-config-$ORG.yaml to be a file, but when the ca serice is started, scripts try to mount it as a directory.
May be the $DOMAIN var is missing?
envSubst "templates/fabric-ca-server-template.yaml" "crypto-config/fabric-ca-server-config-$ORG.$DOMAIN.yaml" "export LDAP_BASE_DN=${LDAP_BASE_DN}"

So how this all could be reproduced.
I use freshly installed Ubuntu 18.04.3 LTS on my vps (I also get this problem on the AWS EC2) with apt-get update && apt-get upgrade
Then I create the 'ubuntu' user and add it to sudoers.

After that I just follow the fabric-starter installation instructions:

sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
sudo apt update
sudo apt-get install docker-ce

sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

sudo usermod -aG docker ${USER}


sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Then I logout/login as the ubuntu and clone the fabric-starter:

git clone https://github.com/olegabu/fabric-starter
cd ./fabric-starter/

The first step is OK:

./clean.sh
./generate-orderer.sh
docker-compose -f docker-compose-orderer.yaml up

Then I open another console and run the
./generate-peer.sh
It exits with the following error:

...

bash: crypto-config/fabric-ca-server-config-org1.yaml: Is a directory
Error occurred. See console output above.

And yes, that's so: the crypto-config/fabric-ca-server-config-org1.yaml is the directory. If I delete it and create the empty file the ./generate-peer.sh fills it with yaml but then it tries to mount the fabric-ca-server-config-org1.yaml, it occures to be a file and the script exits with error nevertheless.

Explicit exporting the COMPOSE_PROJECT_NAME, ORG and all the stuff does not help either.
