Gettting Null values from JsonDocument

Created by: VishBK

This is my code:

    Serial.println("Parsing");
    char input[] = "{\"recenttracks\":{\"track\":[{\"artist\":{\"url\":\"https://www.last.fm/music/Daft+Punk\",\"name\":\"Daft Punk\",\"image\":[{\"size\":\"small\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/34s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"medium\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/64s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"large\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/174s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"extralarge\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/300x300/2a96cbd8b46e442fc41c2b86b821562f.png\"}],\"mbid\":\"\"},\"mbid\":\"069536c6-45f6-489f-93ae-916ab1396cbb\",\"name\":\"Castor\",\"image\":[{\"size\":\"small\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/34s/6bf3e1cd10aad29f0f3da398f22d3a23.jpg\"},{\"size\":\"medium\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/64s/6bf3e1cd10aad29f0f3da398f22d3a23.jpg\"},{\"size\":\"large\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/174s/6bf3e1cd10aad29f0f3da398f22d3a23.jpg\"},{\"size\":\"extralarge\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/300x300/6bf3e1cd10aad29f0f3da398f22d3a23.jpg\"}],\"streamable\":\"0\",\"album\":{\"mbid\":\"\",\"#text\":\"TRON: Legacy - The Complete Edition (Original Motion Picture Soundtrack)\"},\"url\":\"https://www.last.fm/music/Daft+Punk/_/Castor\",\"@attr\":{\"nowplaying\":\"true\"},\"loved\":\"0\"},{\"artist\":{\"url\":\"https://www.last.fm/music/Mac+Quayle\",\"name\":\"Mac Quayle\",\"image\":[{\"size\":\"small\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/34s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"medium\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/64s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"large\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/174s/2a96cbd8b46e442fc41c2b86b821562f.png\"},{\"size\":\"extralarge\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/300x300/2a96cbd8b46e442fc41c2b86b821562f.png\"}],\"mbid\":\"\"},\"date\":{\"uts\":\"1641801521\",\"#text\":\"10 Jan 2022, 07:58\"},\"mbid\":\"ac7937d9-7065-4f42-b715-b7b9195f80dc\",\"name\":\"1.1_4-hateurself.ra\",\"image\":[{\"size\":\"small\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/34s/fbe7813f8258abdeeaae93402d8a03fc.jpg\"},{\"size\":\"medium\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/64s/fbe7813f8258abdeeaae93402d8a03fc.jpg\"},{\"size\":\"large\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/174s/fbe7813f8258abdeeaae93402d8a03fc.jpg\"},{\"size\":\"extralarge\",\"#text\":\"https://lastfm.freetls.fastly.net/i/u/300x300/fbe7813f8258abdeeaae93402d8a03fc.jpg\"}],\"url\":\"https://www.last.fm/music/Mac+Quayle/_/1.1_4-hateurself.ra\",\"streamable\":\"0\",\"album\":{\"mbid\":\"44e399d5-30d5-4098-885d-a7331beb7b61\",\"#text\":\"Mr. Robot, Vol. 1 (Original Television Series Soundtrack)\"},\"loved\":\"0\"}],\"@attr\":{\"user\":\"VishBK\",\"totalPages\":\"48780\",\"page\":\"1\",\"perPage\":\"1\",\"total\":\"48780\"}}}";
    DynamicJsonDocument doc(4096);
    DeserializationError error = deserializeJson(doc, input);
    if (error) {
        Serial.print("deserializeJson() failed for LastFM: ");
        Serial.println(error.c_str());
    }
    JsonObject parsed = doc["recenttracks"]["track"][0];
    serializeJson(parsed, Serial);

and this is what parsed prints out:

}

However, I cannot access anything else in the JSON, such as parsed["image"][1]["#text"], it just returns null. I've checked the size with the assistant, and even the assistant's code is not working. Any ideas what the problem is?
