Trying to get property of non-object error but works when page is refreshed

I get the error in the title sometimes but when I refresh a few times, my application works again.

Laravel.log shows this:

[2016-12-19 13:17:22] local.ERROR: exception 'ErrorException' with message 'Trying to get property of non-object' in
