I am trying to load a file into an application but while loading it throws an error

    Roughly two possible explanations: Either there’s a bug in the data you are trying to load, or there’s a bug in Apache Pentaho-kettle. – Ole V.V. Nov 08 '22 at 17:24

  • I don’t know Pentaho so don’t know much about that error. Most of what I do know is here: [What is a NullPointerException, and how do I fix it?](https://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it) – Ole V.V. Nov 15 '22 at 07:09
