难以在空手道中获取功能文件的有条件调用

Question

难以在空手道中获取功能文件的条件调用。

很难弄清楚为什么该语法不编译。有什么想法吗？

* def authenticator = read('classpath:features/functions/oauth2.feature')
* def oauth = cloud_envs.includes(env) ? karate.call(authenticator) : {}

空手道。CALL可以自己工作正常。无论我尝试什么，都只会失败。

错误是：

* def oauth = cloud_envs.includes(env) ? karate.call(authenticator) : {}0.031
js
js failed:
>>>>
01: cloud_envs.includes(env) ? karate.call(authenticator) : {}

classpath:features/group_info_queries.feature:10

由于此调用在同一测试中起作用，因此似乎应该有效：

* def token = cloud_envs.includes(env) ? 'Bearer ' + oauth.accessToken : 'n/a'

我能够以这种方式工作。不知道为什么我必须这样黑客。丑陋，但有效。

* eval
"""
var tokResponse = karate.call('functions/oauth2.feature')
var emptyResponse = {tokResponse: ''}
if (tokResponse) {
  karate.set('oauth', tokResponse)
} else {
  karate.set('oauth', emptyResponse)
}
