It seems, for some reason, the dovi_tool can't generate a rpu from a Resolve hdr10plus json directly but if you just inject the resolve json to an hevc file and then extract it to a new json file, it works.
So either you do that or export a DV XML instead, or you can use my old RPU scene cuts: https://drive.google.com/file/d/15jug36 ... drive_link
