this is VerifyError class in ts.

export class VerifyError extends Error {
    public readonly code: number;
    public readonly state? : string;
    constructor(message: string, code: number, state?: string) {
        super(message);
        this.code = code;
        this.state = state;
        Object.setPrototypeOf(this, VerifyError.prototype);
    }
}

i found that when i remove add on properties ex. code & state or using Error class directly it fine.

export class VerifyError extends Error {
    constructor(message: string) {
        super(message);
        Object.setPrototypeOf(this, VerifyError.prototype);
    }
}

for a class above it's work, i got error message from curl command and java console print out error.

i found on, moleculer-java-1.2.27, moleculer-java-web-1.3.11.

For addition, here is hello.service.ts

import { Context, ServiceSchema } from "moleculer";
import { VerifyError } from "./VerifyError";

const helloService : ServiceSchema = {
    name: "test",
    actions: {
        greet() {
            return {message: "greeting"};
        },
        verify() {
            //this not work when using java gateway call node
            return Promise.reject(new VerifyError("Verify Error",-99,"error"));
        },
    }
};

export = helloService;
