Hi, at Graphcool, we have the use case, that sometimes we want to send
data
ANDerrors
on thepayload
ofSUBSCRIPTION_DATA
at the same time.This is especially needed for our permissions system, where it could be that the requesting client is only allowed to see some fields on a query. In that case we don't want to disable all other fields, so we send the allowed fields and an error that explains why some fields are null.
This PR just makes sure, that if there is the
errors
property,data
is not just nulled, but is actually checked if there is data.
