   I think I've run into the same issue, but I can replicate with a much 
simpler case for replication:
   To confirm this is a parsing issue I used this query to generate the test 
string:
   ```
       SELECT *
       FROM cypher('testing_graph', $$
        CREATE (c:car { name: '4wd', wheels: ["a",["d"]] })
           RETURN c
       $$) as (c agtype);
   ```
   Returns
   `{"id": 1125899906842627, "label": "car", "properties": {"name": "4wd", 
"wheels": ["a", ["d"]]}}::vertex`
   
   The following test case added to `drivers/nodejs/nodejs/test/Agtype.test.ts` 
will fail:
   ```
   test('Nested Array Parsing', () => {
       expect(AGTypeParse('{"id": 1125899906842627, "label": "car", 
"properties": {"name": "4wd", "wheels": [ "a", ["d"] 
]}}::vertex').get('id')).toBe(1125899906842627)
       expect(AGTypeParse('{"id": 1125899906842627, "label": "car", 
"properties": {"name": "4wd", "wheels": [ "a", ["d"] 
]}}::vertex')).toStrictEqual(new Map<string, any>(Object.entries({
         id: 1125899906842627,
         label: 'car',
         properties: new Map(Object.entries({ name: '4wd', wheels: ['a', ['d']] 
}))
       }));
     })
   ```
   
   The first `expect` is there just to confirm the return Map is completely 
malformed rather than a minor quirk causing `StringEquals` to fail.
   
   The object that does come back looks like this:
   `Map(2) { 'name' => '4wd', 'properties' => [ 'a', [ 'd' ] ] }`
