Second run of dbt snapshot missing valid from/to columns

[Malakai13]

I have a snapshot that looks like this:

{% snapshot my_snapshot %}

{{
    config(
        target_schema='my_schema',
        unique_key='TaskId',
        strategy='timestamp',
        updated_at='LastModified',
        snapshot_meta_column_names={
            "dbt_valid_from": "EffectiveStartDate",
            "dbt_valid_to": "EffectiveEndDate"
        }
    )
}}

select *
from {{ ref('stg_tasks') }}

{% endsnapshot %}

It creates the table correctly the first time, with the EffectiveStartDate/EffectiveEndDate columns. But the second time I run this, I get this error.

Snapshot target is missing configured columns (missing "dbt_valid_from", "dbt_valid_to"). See https://docs.getdbt.com/docs/build/snapshots#snapshot-meta-fields for more information.

It looks like some column check is still looking for the original dbt_valid_from/dbt_valid_to columns rather than the override.

My requirements.txt:

dbt-core==1.9.*
dbt-sqlserver==1.9.*
