Thanks for reporting this @dave-connors-3 !

This looks similar to https://github.com/dbt-labs/dbt-docs/issues/486. If you use Chrome, can you see errors in the Console similar to this?

TypeError: Cannot read properties of undefined (reading 'resource_type')
TypeError: Cannot read properties of undefined (reading 'length')

### Reprex

`models/my_test_model.sql` ``` select 1 as id ``` `models/_unit.yml` ``` unit_tests: - name: my_unit_test given: [] model: my_test_model expect: rows: - {id: 1} ``` ```shell dbt docs generate dbt docs serve ```

Here's the error messages I got:

Based on the error, it's possible that we're not populating the catalog or manifest appropriately. We had a fix awhile back around re-parsing when a fixture is changed, that could have affected this. It can't find the key and attempts to access an attribute on undefined following that.

This may actually be a fix in dbt-core, not in dbt-docs.
