Hi osquery team, we are suffering the problem when we start osuqeryd on host with err Error reading config: Cannot parse JSON: The document root must not be followed by other values. Offset: 4 it looks like the --tls_hostname has some problem because it works after i changed one, but the current one not working.

It sounds like you may be mixing up the flagfile (uses flags like

--tls_hostname

) and the config file (uses JSON)
