I can't get the tool to do anything. I get the following error when I try to execute /opt/gitlab/embedded/bin/mattermost with or without options.
panic: invalid character '<' looking for beginning of value
I had this error with the 2.0 release and it is still there in the 2.1 release.
Installation is the latest version released with GitLab yesterday... GitLab 8.6 / Mattermost 2.1
