PouchDB find error: array selecting null

[SourceR85]

Error when selecting array against null value:

it("should not throw", async () => {
  const db = context.db;

  await db.put({ _id: '1', field: null });

  // FIXME: exception is thrown if documents field is `null`
  //        and selector contains an array
  const resp = await db.find({
    selector: { field: ["what"] }
  });

  resp.docs.should.have.length(0);
});

     TypeError: Cannot read properties of null (reading '0')

Probably same root cause as in #8898

With CouchDB 3.1.2 (same used in GH CI workflows):

# database connection
db=http://admin:password@localhost:5984/test

# write document
curl -s -H "Content-Type: application/json" -X PUT $db/1 -d '{"field":null}' | jq .

# query database
curl -s -H "Content-Type: application/json" -X POST $db/_find -d '{"selector":{ "field":["what"] }}' | jq .

Output:

{
  "ok": true,
  "id": "1",
  "rev": "1-d092ffa43b2c0bde2d792bf5d6570a2c"
}
{
  "docs": [],
  "bookmark": "nil",
  "warning": "No matching index found, create an index to optimize query time."
}
