Changing Default JsonSerilizerOptions

[HarCass]

Hello, I'm currently using Elsa 3's server with the studio and I'm wondering if there is a way to change the default JsonSerializerOptions that Elsa uses in its HttpResponse activities, I need it to ignore when writing null values and use camel case. I couldn't seem to find a way to apply this globally within Elsa either in code or studio. At the moment I am adding attributes to my objects to achieve what I want, however this is very long winded and I was wondering if I was just missing some easy way to do this.

I couldn't find anything in the docs about this or a discussion about it, I have tried something like this to no avail

builder.Services
    .AddElsa(elsa =>
    {
        elsa.Services.ConfigureHttpJsonOptions(options =>
        {
            options.SerializerOptions.DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull;
            options.SerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
        });
    });

Any help is appreciated, thanks in advance!

ConfigureHttpJsonOptions configures ASP.NET Core's HTTP JSON options, but it does not control Elsa's Write HTTP Response activity. In Elsa 3.0.0, the activity's JSON content factory calls JsonSerializer.Serialize(content) without passing any configured options, so there is no supported global option for camel-case naming or null omission on that activity.

For that version, the practical workaround is to serialize the response body yourself with the JsonSerializerOptions you need and pass the resulting string to Write HTTP Response. If you need this everywhere, replace Elsa's IHttpContentFactory for application/json with your own implementation that serializes with those options.
