Why syntaxError: invalid syntax Occurs when Login to openstack dashboard?

I got issue when running openstack horizon. I failed to log in horizon after setting all requirements and i got SyntaxError in /var/log/apache/error.log.

mod_wsgi (pid=5342): Failed to exec Python script file '/usr/share/openstack-dashboard/openstack_dashboard/wsgi.py'.
mod_wsgi (pid=5342): Exception occurred processing WSGI script '/usr/share/openstack-dashboard/openstack_dashboard/wsgi.py'.

File "/usr/lib/python3/dist-packages/openstack_dashboard/local/local_settings.py", line 137
   'enable_router': False,
SyntaxError: invalid syntax

Why the SyntaxError : invalid syntax occurs?

I solve the problem after i checked the /etc/openstack-dashboard/local_setting.py.

OPENSTACK_NEUTRON_NETWORK = {
    ...
    'enable_router': False,
    'enable_quotas': False,
    'enable_ipv6': False,
    'enable_distributed_router': False,
    'enable_ha_router': False,
    'enable_fip_topology_check': False,
}

I didn't remove the ... in OPENSTACK_NEUTRON_NETWORK. After i remove it, the horizon works fine.
