Logged out of my phone beacause of FRP that i set with my custom dpc.

I created a custom dpc and was testing it . In order to validate the frp i did a factory reset on my device from the boot menu . I got a lock at the top asking for the device owner's mail id . It entered it.
But it kept on saying " please sign in with on of the owner's account for this device"
I mean how can it be wrong it is hard coded in my dpc code. 
I am really annoyed would really appreciate some help . 


P.S. -> The phone was mint stock didnt had any mail id set, before installing the dpc.
