Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with

Adding the list() function after the join syntax solves this, or you can simply not use the join...

This is due to a mismatch between your version of Terraform and the intended version of Terraform for this release. The next release will solve this.
