When I read the tif file using pure sql, the shema of the dataframe prints wrong and cannot read the data.

val readSql =
        s"""
           |CREATE OR REPLACE TEMPORARY VIEW my_raster
           |USING raster
           |OPTIONS (
           |paths='LC08_L2SP_126033_20220408_20220412_02_T1_SR_B2.TIF',
           |catalog_col_names='red',
           |tile_dimensions='256,256'
           |)
           |""".stripMargin
val source = spark.sql(readSql)
source.printSchema()
source.show(10, false)

Print
