title: Collection contains no element matching the predicate
body: <p>I'm using the Room library, and I'm getting the following error message when I try to build the app:</p>
  
  <pre><code>e: [kapt] An exception occurred: java.util.NoSuchElementException: Collection contains no element matching the predicate.
  </code></pre>
  
  <p>Here is a more detailed error message:</p>
  
  <pre><code>FAILURE: Build failed with an exception
  * What went wrong:
  Execution failed for task ':app:kaptDebugKotlin'.
  &gt; Compilation error. See log for more details
  </code></pre>
  
  <p>I isolated the problem in the code to be somewhere in the following, although I don't know what exactly is throwing this exception:</p>
  
  <pre><code>package com.example.pomoplay

      abstract fun categoryDao(): CategoryDao

          private var INSTANCE: PomoPlayDatabase? = null
