This is my guess


Your code (LOCATION "s3://<bucket-name>/<folder-name>/parquet_file/) is likely pointing to a single Parquet file instead of the entire folder containing partitioned data.
try this

CREATE TABLE table_name
(
  col1 type1,
  col2 type2,
  col3 type3,
)
USING parquet
PARTITIONED BY (col4 type4)
LOCATION "s3://<bucket-name>/<folder-name>/"  -- Include trailing slash for the folder
