Appium WD proxy with winappdriver 1.2.99.0

Hi team I can’t overcome next issue:
I’m using WinnAppDriver in scope Appium (Appium version 1.22,3 winappdriver automatically installed with appium package 1.2.0)
Currently I’m investigation update winappdriver by self install without appium update
when I download and winappdriver v1.2.1 in same directory all is ok
but when I download and install latest experimental 1.2.99.0 I always see error

when I start winappdriver via WinAppDriver.exe and try to create
new WindowsDriver( new URL( “http://127.0.0.1:4723”), caps);
all works fine
Any thoughts ?
