>                 URL: https://issues.apache.org/jira/browse/SPARK-40282
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 3.3.0
>            Reporter: M. Manna
>            Priority: Blocker
>         Attachments: SparkApplication.kt, retailstore.csv

> *Problem Description*
> as part of contract mentioned here, Spark should be able to support {{IntegerType}} as an argument in StructType.add method. However, it complaints with {{scala.MatchError}} today.
>  
> If we call the override version which access String value as Type e.g. "Integer" - it works.
> *How to Reproduce*
>  # Create a Kotlin Project - I have used Kotlin but Java will also work (needs minor adjustment)
>  # Place the attached CSV file in {{src/main/resources}}   
>  # Compile the project with Java 11
>  # Run - it will give you error.
>  # Now change line (commented as HERE) - to have a String value i.e. "Integer"
>  # It works
> *Ask*
>  # Why does it not accept IntegerType, StringType as DataType as part of the parameters supplied through {{add}} function in {{StructType}} ?
>  # If this is a bug, do we know when the fix can come?
