Test name string error when using vars to pass test name

The context of why I’m trying to do this

I have created a generic test inside of a package. I want this test update to this package is optional and configurable with the use of global vars inside the dbt_project.yml.

What I’ve already tried

  • this test should be called in a model .yml config file via this reference: package_name.test_name (this works when i hard code this test name)
  • i then put a var in the dbt_project.yml:
vars:
  'custom_dbt_test': package_name.test_name

then i reference this var to apply this test in a model .yml config file

tests:
    - "{{ var('custom_dbt_test') }}"

Error message that I get

Compilation Error
  Invalid generic test configuration given in models/...: 
  Test name string did not match expected pattern: {{ var('custom_dbt_test') }}
        @: UnparsedModelUpdate(original_file_path='mode...ne)
