[Bug] Schema Inspect did not return column details

## Description

Ran the following prompt -

Look at SNOWFLAKE_SAMPLE_DATA.TPCH_SF1 and create a detailed reporting app for me using dbt medallion architecture

It ran schema_inspect tool as part of the understanding, but this did not return Column details (I don't know if this is expected, if not, why did the agent say that it couldn't get column info)
