Empty atlantis.yaml in some PRs

Bug report

We are facing a issue that some atlantis.yaml for some PRs are being generated empty.

We are using this script to generate the config:

# Script name
LOGGING_NS="$0"

echo "[${LOGGING_NS}] ==> Generating atlantis configuration for the current project...\n"

terragrunt-atlantis-config generate --autoplan --ignore-parent-terragrunt --parallel --create-project-name --terraform-version $TERRAFORM_VERSION --output pre-atlantis.yaml
cat pre-atlantis.yaml | grep -vE ".*(\/terragrunt|\/kubernetes)\.hcl$" | grep -vE ".*modules.*" > atlantis.yaml

echo "[${LOGGING_NS}] > + Atlantis config updated...\n"

The script is executed before every plan, apply, etc.
Any thoughts?

parsing atlantis.yaml: version: is required. If you've just upgraded Atlantis you need to rewrite your atlantis.yaml for version 3
I'm receiving this because atlantis.yaml is being created, but without any content
