appium/appium

Hi everyone. I'm in need of some appium help. I have appium authenticating an app with biometrics enabled on android. The app running in Sauce Labs uses a different call to authenticate biometrics than a local emulator. The call to Sauce Labs works perfectly, but when doing the calls on a local android emulator, they fail to authenticate. The Android emulator has a fingerprint setup on fingerprint 1.
I am using python and tried,
driver.finger_print(1)
It fails.
I then bypassed driver with the appium http api like this,
http://0.0.0.0:4723/wd/hub/session/<appium_session_id>/appium/device/finger_print

with a json body of,

{
  "fingerprintId": 1
}

and it still fails.
the appium server output is,

[HTTP] --> POST /wd/hub/session/a4488470-2f44-4c51-b145-ec930b10a4fc/appium/device/finger_print
[HTTP] {"fingerprintId":1}

ANY help here would be appreciated. I'm really stuck.
