seems it's a bug around value 0.

SELECT JSON_OBJECTAGG(k: v ABSENT ON NULL WITH UNIQUE KEYS RETURNING jsonb)
FROM (VALUES (1, 1), (10, NULL),(4, null), (5, null),(6, null),(2, 2)) foo(k, v);
return:
{"1": 1, "2": 2}

SELECT JSON_OBJECTAGG(k: v ABSENT ON NULL WITH UNIQUE KEYS RETURNING jsonb)
FROM (VALUES (1, 1), (0, NULL),(4, null), (5, null),(6, null),(2, 2)) foo(k, v);

return
 {"0": null, "1": 1, "2": 2}

But
select json_objectagg(
    k:v absent on null with unique keys returning jsonb )
from (
    values(1,1),(0, null),(3, null),(2,2),(4,null)
) foo(k, v);
return
json_objectagg ----------------------------- {"0": null, "1": 1, "2": 2}

the last query "returning jsonb" should be   { "1" : 1, "2" : 2 } ?
