You wrote this dbt model config but get an error:

config(
  materialized='table',
  partition_by='order_date',
  cluster_by=['customer_id']
)

What is the likely cause of the error?

Bpartition_by should be a dictionary, not a string

Cmaterialized cannot be 'table'

Dcluster_by should be a string, not a list

Step-by-Step Solution

Solution:

Step 1: Check partition_by syntax
Partitioning requires a dictionary with 'field' and 'data_type', not just a string.
Step 2: Verify cluster_by and materialized
cluster_by as a list is correct, and materialized='table' is valid.
Final Answer:
partition_by should be a dictionary, not a string -> Option B
Quick Check:
partition_by needs dict, not string [OK]

Quick Trick: partition_by needs dict with field and data_type [OK]
