I have a Field API field and I have attached it to an entity. This field has multiple fields in it. When I submit the form without all fields filled I get the "This value should be of the correct primitive type." error.
Is this a bug or am I doing something wrong? I was having trouble with serialized field for storing metadata but I've been able to get around it by setting it to computed field. But I cannot do that in this case.

Following discussion thread in #52, and being broadly in the same scenario (custom entity reference field type and a widget that extends EntityReferenceAutocompleteWidget), for me the validation error could be avoided by making $form_state->setValueForElement($element, ['target_id' => null]) when the field is submitted empty, in the validate method.
