@karlwir I think we should use safe-stable-stringify per winstonjs/logform#98 -- what do you think?

[karlwir]

@DABH Agree, my mistake. PR updated.

Looks reasonable to me and this is consistent with the changes we made in logform, so I'm okay with merging this. Thanks!

I love you @karlwir

I needed this fix today 😆

Hi! Im getting

TypeError: stringify.configure is not a function at Format.transform (/node_modules/logform/json.js:27:35)

I'm using winston 3.6.0 and morgan 1.10.0

On Windows it works properly, but on linux breaks.

Thanks for reporting that. The OS difference initially makes me wonder if there might be a filename reference with incorrect casing somewhere.

[SamuelGaona]

It wasnt happening on winston@3.5.1, tho.

It's definitely possible that the issue was newly introduced, and knowing that is quite helpful. I was just offering another signpost to possibly help with debugging as I don't have the time to do a full debug on it at the moment.
