Source named xxx which was not found

Help

The problem I’m having

I added a source and model in a yml file and added a sql (or pyspark) file that uses the defined source. All very basic, but I keep getting this error:

Compilation Error
    Model ‘model.governance_dbt.triple_a’ (models/bronze/breeding/triple_a/triple_a.py) depends on a source named ‘aeu.bull_triple_a’ which was not found

I can’t figure out what I am doing wrong. Other models in my project are similar and work fine. Location and directory structure are also similar. Both my files are in the same directory.
Any suggestions are welcome!

The context of why I’m trying to do this

Just want to add a simple model

What I’ve already tried

dbt parse(or dbt run) without the new model files works fine. But as soon as I add the model, it fails with the above mentioned error.
Instead of using pyspark, I tried sql, but same result (as expected)

The files for the model I am adding

file: bull_triple_a.py

import pyspark.sql.functions as f

def model(dbt, session):
    df = dbt.source("aeu", "bull_triple_a").filter(f.col("expiry").isNull())
    return df

file: bull_triple_a.yml

models:
  - name: bull_triple_a
    config:
      submission_method: job_cluster
      job_cluster_config: "{{ var('job_cluster_config_pool_breeding_small_prd') if target.name == 'prod' else var('job_cluster_config_pool_breeding_small_dev') }}"
      create_notebook: true # Set to true to create a separate notebook for development and testing

sources:
  - name: bull_triple_a
    description: AEU triple A data
    schema: aeu
    tags:
      - breeding
    meta:
      owner: '@BGF'
    database: versioned_{{ 'prod' if target.name in ['prod','staging','lab'] else 'dev' }}
    tables:
      - name: bull_triple_a

You can forget my question. It turns out that I didn’t have the right understanding of the naming mechanism. :frowning:
in db.source I reference aeu, but this does not match with name of the source in the yml, which was bull_triple_a. When I changed it there to aeu, everything works!
