body: <p>I have gone in and checked to make sure the file exists, but I'm not familiar with the not able to verify the signature error:</p>
  <p>Here is the full error:</p>
  <pre><code>Original error: Cannot verify the signature of '/Applications/Appium.app/Contents/Resources/app/node_modules/appium/node_modules/appium-uiautomator2-server/apks/appium-uiautomator2-server-v4.15.0.apk'.

  <p>I'm assuming they go hand in hand, but I'm not super sure.</p>
  <p>I checked for the missing item in the second error, but could not find it. Is there a way that I can find this file somewhere and manually upload it. Or what is the best way to go about solving this issue. I'm quite a novice so this is all pretty new to me (ie. getting a necessary file that does not currently exist in the directory or solving the signature issue)</p>
  <p>I'm currently running appium on the desktop client and have added the file paths for JAVA_HOME and ANDROID_HOME.</p>
