ZigBeeGateway: Assertion `0' failed

I’m currently testing Zigbee with my Matrix Creator. Unfortunately I can’t find a solution for the following error when running the test_zigbee.js:

ZigBeeGateway: ../../../protocol/zigbee_5.7/app/framework/util/af-main-host.c:372: emAfResetAndInitNCP: Assertion '0' failed.

/lib/systemd/system/matrixio-malos-zigbee.service:8: Unknown lvalue ‘After’ in section ‘Install’, ignoring
