How to capture errors in Promise in Java?

[rongrong1000]

    public static void main(String[] args) {
        try (V8Runtime v8Runtime = V8Host.getNodeInstance().createV8Runtime()) {
            v8Runtime.getExecutor("""
                async function a() {
                	bbb()
                }
                
                a()
                """).execute();
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

If an error occurs, the JVM will shut down

If the content of JavaScript is not controlled

What should I do?

Thanks

You may get it by the Promise returned by that execute(), and you must call await() to pump the event loop so that V8 can actually process the async task queue.

Please refer to this doc for detail.
