Hi, I've managed to break the complex set of structs down to the following test case. controller-get crd paths="<path/to/testcase/below>/..." output:stdout currently fails on this one. With the fix it doesn't fail. It's due to the use of an anonymous struct.

// +groupName=test
package config

import (
	metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
)

type ExampleSpec struct {
	Service Service `json:"service"`
}

type Example struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata,omitempty"`

	Spec ExampleSpec `json:"spec,omitempty"`
}

type Service struct {

	// +optional
	Foobar struct {
		// placeholder
	} `yaml:"foobar" json:"foobar"`
}

@rkettelerij please update pkg/crd/testdata/cronjob_types.go with an anonymous struct to test this

/ok-to-test

ctx.pkg.AddError(loader.ErrFromNode(fmt.Errorf("encountered non-top-level struct (possibly embedded), those aren't allowed"), structType))
return props
}
