Mkrdir: cannot create directory /run/user/1001 : Permission denied

I created a daemon snap but it show mkrdir: cannot create directory /run/user/1001 : Permission denied when I start it and my service is inactive.

part of snapcraft.yaml file is like this:

MyApp:
    adapter: full
    command: usr/bin/MyApp
    command-chain:
      - bin/desktop-launch
    daemon: simple
    restart-condition: always
    plugs: [home, unity7, x11, network, network-bind]
    environment:
      DISABLE_WAYLAND: 1

How can I get rid of this permission?
