I updated oreo build, you can find it here in this topic, pie build failed, tried few times. Try to not setup screen lock and login /e/ at first setup screen, try to use you phone without it and add it later from settings menu if you really need it, also the problem can be with your firmware if you flash oreo rom, and your stock rom was pie, maybe you should try flash your oreo stock rom if it is availiable, cause i dont know how it works with sony devices.
well i cant help you with it, im only put device codename in docker script and it build rom automatically, as this build not official one, there is no any support, i dont own these devices, so all testing for it is on you side, you can try use mine, build your own, or wait for official one.
