File Format JSON - Table fails to register

Describe the bug

When you set the file_format to JSON and complete a DBT run, the JSON files get written to the correct path on S3 however, the glue data catalogue fails to get updated with the new table.

Steps To Reproduce

Set the model properties as follows:

{{ config(
    partition_by=['year','month','day','hour'],
    file_format='json',
    materialized='table',
    custom_location='s3://' + var('AWS_ACCOUNT_ID') + '-' + var('AWS_REGION') + '-partner-data/egress/posting_event'
) }}

Expected behavior

Like when the file_format is parquet or hudi I would expect the process to complete without error and register my new table in the glue data catalogue.

Screenshots and log output

Error returned to the console is: IllegalArgumentException: Can not create a Path from an empty string
