Amazon.Lambda.Serialization.SystemTextJson.LambdaJsonSerializer options customizations ignore when in debug mode

[rpopovych]

I am trying to use custom serialization options in the new Amazon.Lambda.Serialization.SystemTextJson.LambdaJsonSerializer. It looks like they are ignored in Debug mode (LAMBDA_NET_SERIALIZER_DEBUG = true).

public class LambdaSerializer : Amazon.Lambda.Serialization.SystemTextJson.LambdaJsonSerializer
{
    public LambdaSerializer() : base(Customizer) { }

    private static void Customizer(JsonSerializerOptions options)
    {
        options.Encoder = JavaScriptEncoder.UnsafeRelaxedJsonEscaping;
    }
}

aws-lambda-dotnet/Libraries/src/Amazon.Lambda.Serialization.SystemTextJson/LambdaJsonSerializer.cs

Lines 74 to 88 in 65ba2c9

	JsonSerializer.Serialize(utf8Writer, response);
	var jsonDocument = debugWriter.ToString();
	Console.WriteLine($"Lambda Serialize {response.GetType().FullName}: {jsonDocument}");
	var writer = new StreamWriter(responseStream);
	writer.Write(jsonDocument);
	writer.Flush();
	}
	}
	else
	{
	using (var writer = new Utf8JsonWriter(responseStream))
	{
	JsonSerializer.Serialize(writer, response, _options);

I'm addressing this issue with this PR #636 that also addressing the camel casing issue.

Version 2.0.0 of Amazon.Lambda.Serialization.SystemTextJson is out with the change. Main take away it update the serializer class to be DefaultLambdaJsonSerializer.

I also published a blog post that has a section describing the change.
