Issue

I am trying to set an entry in a module in my suitecrm instance the method am using is this

static Future<bool> createTurnoVigilante({
    required String nombre,
    required String inicioFinalTurno,
    required int turnoExtra,
    required String rostroVigilanteBase64, // Imagen en Base64
    required String latitud,
    required String longitud,
    required String uuid,
  }) async {
    final String? decryptedSessionId = await AuthenticationService.getDecryptedSessionId();
    final String? suitecrmUrl = await _storage.read(key: 'suitecrm_url');

    if (decryptedSessionId == null || suitecrmUrl == null) {
      print("No se pudo obtener la sesión o la URL de SuiteCRM.");
      return false;
    }

    final Uri endpointUri = Uri.parse('$suitecrmUrl/service/v4_1/rest.php');
    final response = await http.post(
      endpointUri,
      headers: {'Content-Type': 'application/x-www-form-urlencoded'},
      body: {
        'method': 'set_entry',
        'input_type': 'JSON',
        'response_type': 'JSON',
        'rest_data': jsonEncode({
          'session': decryptedSessionId,
          'module_name': 'tuvi_turnos_vigilantes',
          'name_value_list': [
            {'name': 'name', 'value': nombre},
            {'name': 'mao_inicio_final', 'value': inicioFinalTurno},
            {'name': 'mao_turno_extra', 'value': turnoExtra.toString()},
            {'name': 'mao_rostro_vigilante', 'value': rostroVigilanteBase64}, // Image in Base64
            {'name': 'latitude_c', 'value': latitud},
            {'name': 'longitude_c', 'value': longitud},
            {'name': 'mao_uuid_c', 'value': uuid},
          ],
        }),
      },
    );

    if (response.statusCode == 200) {
      final data = json.decode(response.body);
      if (data['id'] != null) {
        return true;
      }
    }
    return false;
  }

also I try to make the request in postman and in both the entry is created but the image in the module don't display any image and in the data base the value in the field of the base64 image is the base64 code of the image, maybe am missing something?
