When trying to convert static mapping to C# code, I ran into an exception when the body is a top-level array rather than a pure string or a (non-array) JSON object.

The problem is that this code doesn't distinguish between arrays and objects, and assumes that every non-null that isn't a string is an object:

case BodyType.Json:
    if (bodyData.BodyAsJson is string bodyStringValue)
    {
        sb.AppendLine($"        .WithBody({ToCSharpStringLiteral(bodyStringValue)})");
    }
    else if (bodyData.BodyAsJson is { } jsonBody)
    {
        var anonymousObjectDefinition = ConvertToAnonymousObjectDefinition(jsonBody);
        sb.AppendLine($"        .WithBodyAsJson({anonymousObjectDefinition})");
    }
                                                                                      
    break;

My solution is to load a JToken instead of a JObject in ConvertToAnonymousObjectDefinition, which seems like the original intention given that ConvertJsonToAnonymousObjectDefinition (which is defined in an internal class) expects a JToken and isn't called anywhere else in the code.
