Double-serialization of string as input to durable activities

When sending a string as an input to a Durable activity, we get double serialization - "Seattle" becomes ""Seattle""

Code:

    @FunctionName("HelloCities")
    public List<String> runOrchestrator(
            @DurableOrchestrationTrigger(name = "context") TaskOrchestrationContext ctx, 
            final ExecutionContext context) {
        return ctx.callActivity("SayHello", "Seattle", String.class).await();
    }

    @FunctionName("SayHello")
    public String sayHello(
            @DurableActivityTrigger(name = "name") String name,
            final ExecutionContext context) {
        context.getLogger().info("Saying hello to " + name + ".");
        return "Hello " + name + "!";
    }

Returns "Hello "Seattle""

首先，使用报告中所示的 runOrchestrator callActivity("SayHello", "Seattle", String.class) 路径和 sayHello durable activity trigger 重现该问题。跟踪字符串输入的序列化和反序列化过程；当 activity 接收到不带额外引号的 Seattle 并返回 "Hello Seattle!" 时，即表示完成。
