Karate Karate-config.js不是js函数

我正在尝试使用空手道进行e2e测试,并已从最低设置开始。我想在中创建一些配置项 karate-config.js 用于测试,但karate报告该文件不是js函数,因此测试无法获取配置:

Warning: Nashorn engine is planned to be removed from a future JDK release

org.opentest4j.AssertionFailedError: -unknown-:4 - javascript evaluation failed: priceBaseUrl, ReferenceError: "priceBaseUrl" is not defined in <eval> at line number 1

这是我的 :

function fn() {

    return {
        priceBaseUrl: "http://localhost:8080"
    };
}

这是我的 insurer.feature 测试:

Feature: which creates insurers

Background:
  * url priceBaseUrl
  * configure logPrettyRequest = true
  * configure logPrettyResponse = true

Scenario: basic roundtrip 

# create a new insurer
Given path 'insurers'
And request { name: 'Sammy Insurance', companyCode: '99' }
When method post
Then status 201
And match response == { resourceId: '#number', version: 0, createdBy: 'anonymousUser' }

* def insurerId = response.resourceId

# get insurer by resource id
Given path 'insurers', insurerId
When method get
Then status 200
And match response == { id: '#(id)', name: 'Sammy Insurance', companyCode: '99' }

InsurerTest.java 试车员:

package karate;

import com.intuit.karate.junit5.Karate;

class InsurerTest {

    @Karate.Test
    public Karate testInsurer() {
        return new Karate().feature("classpath:karate/insurer.feature");
    }
}
