[Regression] dbt run-operation requires the application default credentials

[yu-iskw]

Is this a regression in a recent version of dbt-bigquery?

• I believe this is a regression in dbt-bigquery functionality
• I have searched the existing issues, and I could not find an existing issue for this regression

Current Behavior

dbt-bigquery 1.9 requires the application default credentials even if the executed macro doesn't need to use the credentials.

WARNING:google.auth._default:Authentication failed using Compute Engine authentication due to unavailable metadata server.
08:57:43  Encountered an error while running operation: Database Error
  Runtime Error
    Failed to authenticate with supplied credentials
    error:
    Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information.

Expected/Previous Behavior

I expect we can execute a macro which don't need to access BigQuery without the application default credetials.

Steps To Reproduce

1. Install dbt-core 1.9 and dbt-bigquery 1.9 in the jaffle_shop project
2. Implement a dbt Macro named macros/echo.sql

   {% macro echo() %}
       {% do log("Hello, world!", info=True) %}
   {% endmacro %}
   

3. Execute dbt run-operator echo without the appliction default credentials
   • We can revoke the application default credentials by gcloud auth application-default revoke

Hello @yu-iskw ! Curious what your use case here is as to why you would like us to support this?

Hi @amychen1776,

I don't think a regular dbt project should work without the application default credentials. But, some dbt Packages might need to run dbt run-operation without the application default credentials for unit tests.

I posted an article about how to do unit testing dbt Package in addition to integration tests to dbt Developer Blog before. We can implement unit tests utilizing dbt run-operation, as we implement unit tests in regular programming languages. That approach enables us to directly make sure behaviors dbt Macros. We can also run unit tests in CI as I implemented in yu-iskw/dbt-unittest.

https://docs.getdbt.com/blog/unit-testing-dbt-packages

We consider if a dbt Package supports multiple major warehouses as BigQuery, Snowflake ans so on. And the developers want to run unit tests not only in CI jobs but also their local machines. For instance, first, the repository owner who doesn't mainly use BigQuery on a daily basis has to set the application default credentials in CI jobs. Second, the contributos have to set the application default credentials, even if he/she wants to enhance parts for a warehouse other than BigQuery. I suppose it can be hassle for them. That's why I want dbt-bigquery 1.9 to act as before. That would be helpful, though the behaviro might be directly related to some dbt Package develoeprs.
