The given key was not present in the dictionary. エラー対処法教えてください。

udonsharp sdk3でこちらのスクリプトだと　
[<color=#FF00FF>UdonSharp</color>] Assets/Brick Project Studio/Apartment Kit/Scenes/Scene_02_UdonProgramSources/monbot.cs(70,75): Udon runtime exception detected!
  An exception occurred during EXTERN to 'UnityEngineComponent.__GetComponent__T'.
      Parameter Addresses: 0x0000002C, 0x00000019, 0x0000002B
  
  The given key was not present in the dictionary.

このエラーがでてきてOnPickupUseDown()してもスクリプトが実行されません。
対処法どなたか教えていただきたいです。

この部分がエラーを起こしているみたいです
