[mercedes-wu-wandb]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

commands from dbt project level:
mf health-checks

output:

AttributeError: 'Namespace' object has no attribute 'PROFILES_DIR'

Expected Behavior

✔ Health checks completed.
• ✅ SqlEngine.BIGQUERY - SELECT 1: Success!

Steps To Reproduce

1. Set up a dbt project with a valid profiles.yml.
2. Set the DBT_PROJECT_DIR environment variable to point to the project directory:
   export DBT_PROJECT_DIR=/path/to/dbt/project
3. Set the DBT_PROFILES_DIR environment variable to point to the profiles
   export DBT_PROFILES_DIR=/path/to/profiles/directory
4. Run the following command from the dbt directory:
   mf health-checks

Relevant log output
