When dbt exits, it will return an exit code of either 0, 1, or 2.
|0||The dbt invocation completed without error.|
|1||The dbt invocation completed with at least one handled error (eg. model syntax error, bad permissions, etc). The run was completed, but some models may have been skipped.|
|2||The dbt invocation completed with an unhandled error (eg. ctrl-c, network interruption, etc).|
While these exit codes may change in the future, a zero exit code will always imply success whereas a nonzero exit code will always imply failure.
