fprintd-enroll fails with No devices available.

I'm running Manjaro with KDE Plasma - 5.20.5 in my Lenovo ThinkPad X1 Yoga(1st Gen). I followed the steps in the README.

Installed validity-sensors-tools
Gave access to the usb devices.
Initialized the device.
Tested the LED (It works!)
Tried the validity-sensors-tools.enroll with a blind hope but it didn't work because my sensor is 138a:0090.
Installed fprintd and libfprint-vfs-009x-git (The readme says its libfprint-vfs-0090-git but I couldn't find one in the AUR)
Now when I try fprintd-enroll it fails!!

fprintd-enroll Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available

Let me know if you need more details on something. Kindly help!
