Power BI Refresh Error:
dbt Exit Code 2

What does this error mean?

The dbt process exited with code 2 — a fatal error that prevented dbt from starting a run. This is always a configuration or environment problem: invalid command arguments, a missing or malformed dbt_project.yml, a broken Python environment, or an unhandled internal exception in dbt itself.

Common causes

  • 1Invalid dbt command flags or arguments for the installed dbt version
  • 2A fatal project or profile configuration error
  • 3An unhandled Python exception in the dbt installation

How to fix it

  1. 1Check the dbt output for the specific fatal error message at the top of the log.
  2. 2Verify the dbt command syntax and all flags are correct for your dbt version.
  3. 3Run `dbt debug` to check project and profile configuration.
  4. 4Check for Python environment issues — ensure dbt and its dependencies are correctly installed.

Frequently asked questions

What are the most common causes of dbt exit code 2?

Common causes: invalid Jinja, bad ref() calls, invalid YAML, connection failures, missing environment variables, or CLI/adapter version mismatches. Check the dbt log for the first ERROR line — it identifies the root cause.

Does dbt exit code 2 mean no models ran?

Usually yes — exit code 2 means dbt failed before or during the run. If during compilation, no SQL was executed; if mid-run (e.g., fatal connection error), some models may have run.

How is dbt exit code 2 different from a compile error?

A compile error is one cause — dbt exits with code 2 for any fatal error. Other causes: runtime crashes, system errors, adapter failures. Exit code 2 is the generic 'something went critically wrong' signal.
