The Google service has bugs which means some items can never download, attempts to access the media IDs gets a 500 error. We place offending items in the gphotos.bad_ids.yaml.
However, it is important to distinguish between this and intermittent service failure (as far as is possible anyway). See https://github.com/gilesknap/gphotos-sync/issues/98#issuecomment-516725134 for more discussion.
