I see the e tag in the json, what else should be referenced?
hmm good to know, should make sure the spec is aligned nostr:npub12gyrpse550melzx2ey69srfxlyd8svkxkg0mjcjkjr4zakqm2cnqwa3jj5 nostr:npub13v47pg9dxjq96an8jfev9znhm0k7ntwtlh9y335paj9kyjsjpznqzzl3l8

nothing else, it is as it should, Amethyst is probably not looking for e tags because almost always the reference is an a or r tag
nostr:npub1w0rthyjyp2f5gful0gm2500pwyxfrx93a85289xdz0sd6hyef33sh2cu4x renders the reference just fine

oh interesting, its only looking for highlights in longform or web? nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z
