Converting Json to CSV using ChoETL issue not getting data properly

Question

I'm converting Json complex data to CSV file.

This is my code:

StringBuilder csv = new StringBuilder();

using (var r = new ChoJSONReader(FileNameSample33JSON)
                      .WithJSONPath("$..getUsers[*]", true))
{
    using (var w = new ChoCSVWriter(csv)
                          .WithFirstLineHeader()
                          .WithMaxScanRows(10)
                          .Configure(c => c.ThrowAndStopOnMissingField = false))
    w.Write(r);
}

JSON:

"extension": [
    {
        "Test": "value",
        "value": [ "0", "1", "2" ]
    },
    {
        "Test1": "Test",
        "value": "20"
    },
    {
        "Test2": "Test",
        "value": "35"
    }
]

The issue is values 20 and 35 are missing because in the first object, the value field is a list, while in the subsequent objects, value is not a list. This inconsistency causes the values to be overlooked.

I want all values like

extension_0_value_0	extension_0_value_1	extension_0_value_2	extension_1_value	extension_2_value
0	1	2	20	35

How to fix this issue..?
