How to return data and errors?

[garyrutland]

Hi,

I notice that the library is able to support returning both data and errors but haven't quite seen or figured out how to do it myself?
The error handling docs says to throw either a UserError or UserWarning but if I have a mutation which is doing something in batch it would be good to be able to return data for what succeeded and errors for anything that failed.

Is this currently possible or would it be a feature request?

Thanks,
Gary
