b=sort(select(tuple(id=2,email="B"),id,email),by="id asc,email asc"),
c=merge(get(a),get(b),on="id asc,email asc"),
get(c)
)
{
"result-set": {
"docs": [
{
"EXCEPTION": "Invalid MergeStream - all substream comparators (sort)
must be a superset of this stream's comparator.",
"EOF": true
}
]
}
}
while below sort outside get works

let(
a=select(tuple(id=3,email="C"),id,email),
b=select(tuple(id=2,email="B"),id,email),
c=merge(sort(get(a),by="id asc,email asc"),sort(get(b),by="id asc,email asc"),
on="id asc,email asc"),
get(c)
)
{
"result-set": {
