Relationship fields in
create
andupdate
operations currently acceptnull
as a valid GraphQL input. This is not currently handled correctly, see #5014 .This PR adds tests and clarifies that
null
input is equivalent toundefined
input, e.g. does not set or change the field value.In the future we might need to revisit whether we want to disallow
null
as an input value, or apply different semantics (e.g.null
being equivalent todisconnectAll
in update). This PR is simply setting a well defined baseline to build on.
