Ok so I found a way to monkeypatch my problem. I replaced this line :

jsonapi.rb/lib/jsonapi/active_model_error_serializer.rb

Line 45 in edfb676

attrs = (model_serializer.attributes_to_serialize || {}).keys

with this :
attrs = (model_serializer.attributes_to_serialize || {}).keys.map{|k| k.to_s.underscore.to_sym}

It's ugly, but it's the only way i found to respect JSONAPI and still get errors for field with _ in it.

This isn't fixed in v2.0.0, looks like v1.8 never happened?

I'm running into the same issue

We had to skip over v1.8 because of the breaking changes. Btw, there's #58, nobody weighted on the changes there so it probably got lost.

We can have a small release with this one. @storm-factory did #58 solve your problem?
