[CT-3098] [Bug] Columns are not exported in the json output of dbt list

[frco9]

Is this a new bug in dbt-core?

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

Current Behavior

I have define a model with columns and an enforced contract. When using dbt --quiet list --resource-types model --output json it outputs models definition without its columns

Expected Behavior

When using the list and has columns were defined, I was expecting to get the columns definition.

Steps To Reproduce

Given this model config :

models:
  - name: dataset_test1
    config:
      materialized: table
      contract: { enforced: true }
    columns:
      - name: CTRY_C
        description: This is a column
        data_type: varchar

Then run the following command : dbt --quiet list --resource-types model --output json

Relevant log output

    "name": "dataset_test1",
    "resource_type": "model",
    "package_name": "demo_dbt",
    "original_file_path": "models/example/dataset_test1.sql",

@frco9 Try:

dbt --quiet list --resource-types model --output json --output-keys name columns # whatever else you want

{"name": "my_model", "columns": {"id": {"name": "id", "description": "This is my id column", "meta": {}, "data_type": null, "constraints": [], "quote": null, "tags": []}}}

(This is mentioned in the docs, though only briefly)

It works Thanks ! I thought it would only apply to keys already shown, but indeed it is not !
