The parser report this error:

gsth264parser.c:2086:gst_h264_parser_parse_slice_hdr: couldn't find associated picture parameter set with id: 4
gstvaapidecode.c:1119:gst_vaapidecode_parse_frame: parse error -1

So, your video stream isn't providing the PPS when parsing the slice's NALU

Can you provide more info? like a debug with vaapi*:5
and if you could provide the stream would be great.
