Iceberg table materialization does not work

Steps To Reproduce

        file_format= 'iceberg'
    )

Produces error:

IllegalArgumentException:` Can not create a Path from an empty `string`

System information

As an alternative we can use

    config(
        materialized='incremental',
        incremental_strategy='insert_overwrite',
        file_format= 'iceberg',
    )

As stated in the documentation and code if no partition_by is specified with insert_overwrite strategy then it will overwrite the entire table with new data. Thus it behaves as a table materialization.
