[Regression] 'RedshiftRelation' object has no attribute 'lower'

[Vincent Martinez]

Is this a regression in a recent version of dbt-redshift?

• I believe this is a regression in dbt-redshift functionality
• I have searched the existing issues, and I could not find an existing issue for this regression

Current Behavior

Hello

I'm facing following error for table materialization only (incremental & views are fine) since dbt-version 1.6.0 but I'm not able to understand which change is behind this, reading the release :(

As a prof, I executed the same model with dbt 1.5.9 (working perfectly) and then 1.6.0 (not working)

Any idea why ? It doesn't seem any other library are updated when I updated dbt to 1.6.0 so it make me think it's only related to dbt 🤔

Expected/Previous Behavior

I would expect the run to build the table as shown in the first run with dbt 1.5.9

Steps To Reproduce

cf terminal command above

Hello
Any news about this error ?
Is it linked to package dbt-redshift or is it dbt-core related ?
Thanks !
