[severity:It's more difficult to complete my work]
The TransformSchemaNode callback is called with wrong information in both parameters when more than one property uses a JsonConverter.

public sealed class TheConverter : JsonConverter<int>
{
    public override int Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options) => throw new NotImplementedException();
    public override void Write(Utf8JsonWriter writer, int value, JsonSerializerOptions options) => throw new NotImplementedException();
}

public sealed class TheClass
{
    [JsonConverter(typeof(TheConverter))] public int Prop1 { get; set; }
    [JsonConverter(typeof(TheConverter))] public int Prop2 { get; set; }
}

internal class Program
{
    static void Main()
    {
        var jsonSchemaExporterOptions = new JsonSchemaExporterOptions
        {
            TransformSchemaNode = (context, schema) =>
            {
                Console.WriteLine($"path: $/{string. Join("/", context. Path.ToArray())}/, property name: {context. PropertyInfo?. Name}");
                return schema;
            },
        };
        var options = JsonSerializerOptions.Default;
        var schema = options. GetJsonSchemaAsNode(typeof(TheClass), jsonSchemaExporterOptions);
        Console.WriteLine(schema. ToString());
    }
}

Output is:

path: $/properties/Prop2/, property name: Prop2
path: $/properties/Prop2/, property name: Prop2
path: $//, property name:
{
  "type": [
    "object",
    "null"
  ],
  "properties": {
    "Prop1": true,
    "Prop2": true
  }
}

Output should be:

path: $/properties/Prop1/, property name: Prop1
path: $/properties/Prop2/, property name: Prop2
...
