[Regression] Policy tag error with 1.5.0 on BigQuery

[matfior-finn]

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

Running my models with the latest version of dbt gives me errors about policy tags which we are not using.

Only some models are failing but they do not have anything special about them.

Expected/Previous Behavior

No errors.

Steps To Reproduce

1. Install latest version of dbt
2. Run the models

Thank you for reporting this @matfior-finn ! 🙏

I believe this is the same as #687, so I'm going to close this as a duplicate. We'll be doing a patch release that has the fix soon. Please reach out if it doesn't fix the issue you are seeing and we can re-open this.

You mentioned that you aren't using policy tags. This surprises me, because I think you wouldn't be getting this error otherwise. I'd suggest looking in your project (or dbt packages that you have installed) for configurations like shown below. Regardless, I believe the error messages you are seeing will be solved by the upcoming patch release mentioned above.
