Sorry wasn't able to return sooner. I ended up building from source so that I could get going. Should that `nix` command that @Xitian9 posted still work without messing up...

Folks having these types of issues on more recent releases should check out [setting Winston formatters](https://github.com/namshi/winston-graylog2#upgrading-from-earlier-versions-of-winston-graylog2) and examples in the [end-to-end tests](https://github.com/namshi/winston-graylog2/blob/master/test/e2e.js).

I think it was just assumed that you couldn't set the format at the transport level because [the Winston formatting docs](https://github.com/winstonjs/winston#formats) don't mention or show it.

Suggesting either a custom replacer that detects a circular reference and likely discards it or switch to `util.inspect()`. * [Custom Replacer](https://stackoverflow.com/a/11616993) * [`util.inspect()`](https://stackoverflow.com/a/18354289)
