[Bug] dbt_utils.date_spine gives Python error

[hazvk]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

Running this model and using dbt_utils.date_spine used to work. I now get an error I can't get to the bottom of.

Expected Behavior

Should evaluate and give a table

Steps To Reproduce

With dbt on local machine:

1. Define model as per below

{{
    config(
        materialized = "view" if target.name not in ['prod'] else 'table'
    )
}}




WITH date_list AS
(
{{ dbt_utils.date_spine(
datepart="day",
start_date="TO_DATE('01/01/2008', 'dd/mm/yyyy')",
end_date="TO_DATE(CONCAT(YEAR(CURRENT_DATE) + 6,'-12-31'))"
)
}}

)

SELECT
*
FROM date_list;

2. Install the following packages

databricks-sdk = "==0.17.0"
dbt-databricks = "==1.6.8"

3. Run dbt build -f

Relevant log output

Which database adapter are you using with dbt?

other (mention it in "Additional Context")

Additional Context

Using dbt-databricks==1.6.8

Last seen working on Jan 24th. Then another issue came up that I only just resolved, per issue (and hence why I fixed version of databricks-sdk). I haven't tested this functionality until yesterday, which is when I first noticed it was broken.

Wondering if there is an update on the issue?

[SvenRelijveld1995]

I run into the same error, also databricks 1.7.0 and dbt-core 1.7.14

I got the issue but it's working after upgrade. My versions:

  - installed: 1.8.2
  - latest:    1.8.2 - Up to date!

Plugins:
