Error in base_source_columns

[nam-97]

Describe the bug

When running the model base_source_columns by dbt run, I encounter below error

Steps to reproduce

Expected results

Actual results

Screenshots and log output

System information

The contents of your packages.yml file:

Which database are you using dbt with?

• postgres
• redshift
• bigquery
• snowflake
• trino/starburst
• other (specify: ____________)

The output of dbt --version:

1.8.1

Additional context

The problem locates on the post-hook parameter in the model, since the query to create table still can be run in Snowflake. Probably, the post-hook query is trying to insert more columns than the ones existing in the output object

Are you interested in contributing the fix?

Thanks for raising this.

Would you be able to check the dbt log file and/or Snowflake logs to find the exact statement that failed?

Also got this error in BQ. Error is there: Inserted row has wrong column count; Has 8, expected 5 at [3:1]

Hereby the exact query the db got. Did trim it a bit, but the gest is still there.

Thanks a lot!

OK, so I can definitely see the error now. This is a bug in the code but we are actually not testing it in CI. I will add a new test and release a new patch version soon.

0.12.1 should be available in a bit in the dbt Hub
