@xulongju what does the content of your kong.conf file look like?

@p0pr0ck5 if kong.conf or kong_default.lua include "cassandra_contact_points" ,then run "kong migrations up" is OK if kong.conf or kong_default.lua is not include "cassandra_contact_points" ,then run "kong migrations up" is not work ,and print "Error: ...uite/openresty/luajit/share/lua/5.1/kong/conf_loader.lua:188: bad argument #1 to 'ipairs' (table expected, got nil)"

Hello, I'm currently running into the same issue with Kong 0.10.1. I've got Cassandra client-node encryption working (was able to connect with cqlsh through ssl) but when I try to run kong with ssl verification disabled I receive the same error @xulongju reported. If I run the migrations manually I get the same result.

Same thing here on Kong 0.10.3 - see this in the error logs a lot although the request is a GET so there should not be a body to decode [lua] public.lua:27: get_body_args(): could not decode JSON body args: bad argument #1 to '?' (string expected, got nil), client: n.n.n.n, server: kong, request: "GET /some/path HTTP/1.1", host: "example.com"

thibaultcha commented 6 years ago

if kong.conf or kong_default.lua is not include "cassandra_contact_points"

Why would you remove this property from kong_default.lua? Why would you modify this file at all, even? Please don't.

@ivanpondal If you are still experiencing this on a more recent version of Kong, please open another issue with a reproducible use-case and the actual error you are seeing.

@kevinpgrant That is a completely different issue as per the error log - this does not even happen in the CLI. Anyway, it should be fixed in more recent versions (as of today, 0.13.1).
