UserError Path enters non-object

[bcdroid]

Running a nested query with an array of objects nested within an object fails with "Path enters non-object" with dsq 0.23.0. The same query worked with a previous version of dsq, but I do not know the version number.

Query that fails: dsq a.json b.json 'select name from {0, "people"} where id not in (select id from {1})'

a.json

{
   "people": [
    { "name": "p", "id": "1" },
    { "name": "q", "id": "2"}
  ]
}

b.json

[
  {"id": "1"}
]

The error message is:

If the array is extracted from the object, the modified query does succeed.

Query that succeeds: dsq c.json b.json 'select name from {0} where id not in (select id from {1})'

c.json

[
  { "name": "p", "id": "1" },
  { "name": "q", "id": "2"}
