title: Cannot figure out Crashlytics report
body: <p>Basically I have this displayed in my Crashlytics report.
  This error crashes the app.
  It doesn't show any line of code I written and Google search doesn't help either.</p>
  
  <p>Below are screenshots.
  Both are showing the same thing just different ways of showing data.</p>
