I can't believe it. The logging library bunyan-gelf uses flat module (https://github.com/craftti/bunyan-gelf/blob/master/lib/bunyan-gelf.js) and it crashes the process when objects containing circular references are given. This is a serious problem in my opinion because depending on the data you send to a function you process crashes.

Also wishing this was supported, just realized my own logger has the same issue.

I would suggest sanitizing the data prior to calling Flat.

You can use something like fast-safe-stringify and follow their replacer example. It will still keep it as an object but will replace the circular reference with "[Circular]" {"a":1,"o":"[Circular]"}
