✅ JSON - can't deserialize nullable property if it it's not present

Hello, Is if a nullable property is not present in the JSON the deserialization will fail. Is there a way to make deserialization work if a property is not present?

c#
return new JsonSerializerOptions
{
    PropertyNamingPolicy = JsonNamingPolicy.CamelCase,
    DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull,
};

c#
return new JsonSerializerOptions
{
    PropertyNamingPolicy = JsonNamingPolicy.CamelCase,
    DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull,
};

JSON deserialization for type 'UaDetector.Regexes.Models.Bot' was missing required properties including: 'producer'

can you share the definition of the UaDetector.Regexes.Models.Bot class?

Oops

c#
internal sealed class Bot
{
    public required Regex Regex { get; init; }
    public required string Name { get; init; }
    public required BotCategory? Category { get; init; }
    public required string? Url { get; init; }
    public required BotProducer? Producer { get; init; }
}

c#
internal sealed class Bot
{
    public required Regex Regex { get; init; }
    public required string Name { get; init; }
    public required BotCategory? Category { get; init; }
    public required string? Url { get; init; }
    public required BotProducer? Producer { get; init; }
}
