I have tried specifying the schema and assigning the following mapping to each column type:

• string - StringType()
• date - DateType()
• double - DoubleType()
• bigint - LongType()
• int - LongType()
• decimal(20,2) - LongType()

I have also tried using other spark types for the decimal(20,2), int, bigint, and double columns, however, the error still persists.
