Google Pixel device reboots twice after issuing a reboot command

When I issue a REBOOT command to a Google Pixel, it reboots twice in a row. It happens by using the Java SDK, but I was able to reproduce it by using the Android Management API Explorer as well:

POST https://androidmanagement.googleapis.com/v1/enterprises/LCxxxxxxxx/devices/3ded38daabec2df8:issueCommand?key={YOUR_API_KEY}
{
   "type": "REBOOT"
}

  "enterprises/LCxxxxxxxx/devices/3ded38daabec2df8/operations/1569329132626",
  "metadata": {
  "@type": "type.googleapis.com/google.android.devicemanagement.v1.Command",
  "type": "REBOOT",
  "createTime": "2019-09-24T12:45:32.626Z",
  "duration": "600s",
  "userName": "enterprises/LCxxxxxxxx/users/113818350155522235965"
}

This also happens with an Asus Zenfone.

Thanks in advance for your help!

Solution

Thanks for the report, we're looking into the root cause.

As the mitigation for now, please set a shorter timeout like 30 seconds.
