no warning or error is produced when creating a referencer for a missing field

What happened?

While working on an Equinix Metal Terrajet provider, I created a metal_device project field reference, associated with the metal_project identifier.

// config/device/config.go
package device

import "github.com/crossplane-contrib/terrajet/pkg/config"

func Customize(p *config.Provider) {
        p.AddResourceConfigurator("metal_device", func(r *config.Resource) {
                r.Group = "device"
                r.ExternalName = config.IdentifierFromProvider
                r.References["project"] = config.Reference{
                        Type: "github.com/crossplane-contrib/provider-tf-equinixmetal/apis/project/v1alpha1.Project",
                }
        })
}

The problem is that project is not a valid field for metal_device. The field is project_id.

I received no error messages about this typo. make generate succeeded.

When I eventually discovered the typo and set the field name in the map to project_id, an additional file (apis/device/v1alpha1/zz_generated.resolvers.go) was generated.

How can we reproduce it?

That's due to the look-up mechanism we have for this feature where for each field we check whether there is a referencer field, hence no error if nothing hits the given reference entry. One option could be to validate the whole configuration object before starting any operation.
