 - Fixed a bug where using parameter bindings for `CALL` queries issued through `session.sql` would raise an error.
 - Fixed a bug where `StringType` columns from Iceberg tables were not recognized as max-size strings.
+- Improved the `FileNotFoundError` message raised when `INFER_SCHEMA` returns zero rows so it also points to file format options (`PARSE_HEADER`, `SKIP_HEADER`, `ON_ERROR=CONTINUE`) that can silently filter everything out, instead of only suggesting a missing path.
