The first thing with bash scripts is you need to use a type system. Enforce json as your configuration language. Then have error handling as part of a default shell function library that emits json. All you are doing then is passing bad returns to a function that can emit json and reviewing json configurations for shell script variable definitions. Don't do in shell scripts what you can do in terraform. Don't use ansible/salt/puppet for what can be done in shell scripts. Shell scripts and makefiles go to CI/CD agencies (Jenkins). Ansible, terraform, etc...go to services that specialize in these.
