  • Absent a [mcve] with code that reproduces the problem, we can only point you to [What is a NullPointerException, and how do I fix it?](https://stackoverflow.com/q/218384/3744182). – dbc Oct 29 '20 at 04:42

    Does this answer your question? [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) – dbc Oct 29 '20 at 04:42
  • Were gonna need more than that. NullPointerException is probably the most commonplace exception in java. – Nate T Oct 29 '20 at 05:06
