project riff error java.lang.IllegalStateException：无法创建函数

Question

我正在使用一个非常简单的项目 - 即兴在我的Mac笔记本电脑上运行的minkube。它过去曾经工作过一次。在对函数进行少量更改后，我无法为Function创建bean。我在试图执行该功能的minkube pod中获得了跟踪堆栈跟踪。

将不胜感激任何帮助。不确定，我做错了什么。我有一个简单的node.js函数来计算数字的平方。这似乎工作正常。

@SpringBootApplication
public class FunctionExecutorApplication {    

    @Bean
    Function<Flux<String>,Flux<String>> uppercase(){
        return influx ->
        influx.map(String::toUpperCase);
    }    

    public static void main(String[] args) {
        SpringApplication.run(FunctionExecutorApplication.class, args);
    }
}

项目网址是 https://github.com/jaysara/FunctionExecutor

这是我在minikube日志中看到的堆栈跟踪，其中pod尝试初始化该函数。
