  <p>I got that error when I tried to start the server normally</p>
  <p>I just wrote that on desired capabilities</p>
  <pre><code>{
    &quot;automationName&quot;: &quot;Appium&quot;,
    &quot;platformName&quot;: &quot;Android&quot;,
    &quot;platformVersion&quot;: &quot;9&quot;,
    &quot;app&quot;: &quot;C:\\Users\\lenovo\\Downloads\\eribank.apk&quot;,
    &quot;udid&quot;: &quot;3ce85865&quot;,
  }
  </code></pre>
  <p>What should I do more? Or what is the problem from the beginning?</p>
  <p>Android_Home checked and path too.</p>
