dbt 1.10: Deprecated test syntax prevents using `--warn-error` flag

[physcat]

Problem

With dbt 1.10's improved YAML validation, the current test configuration syntax in stg_ga4__event_page_view.yml triggers a deprecation warning. While this doesn't cause failures by default, it prevents teams from using the --warn-error flag for stricter validation during CI/CD.

Warning Output

❯ dbt parse --warn-error
Compilation Error
  Invalid generic test configuration given in models/staging/events/stg_ga4__event_page_view.yml:
  [WARNING][MissingArgumentsPropertyInGenericTestDeprecation]: Deprecated functionality
  Found top-level arguments to test `not_null`. Arguments to generic tests should
  be nested under the `arguments` property.

Root Cause

The test configuration uses the older inline syntax:

- not_null:
    severity: warn

The updated format uses a config block (see dbt docs on severity):

- not_null:
    config:
      severity: warn

Note: The config block syntax is backward compatible and works with older dbt versions, so this change won't break compatibility for users not yet on dbt 1.10.

Impact

• Blocks use of --warn-error flag for strict validation in CI/CD pipelines
• dbt 1.10's improved validation now detects and warns about this older syntax
• Future dbt versions may remove support for the deprecated syntax
