如何解决从Postman转换而来的运行k6负载测试失败
我使用Postman将k6集合转换为负载测试工具postman-to-k6的脚本。运行k6测试失败，并显示以下错误消息：
ERRO[0016] TypeError: Cannot read property 'set' of undefined or null
Run at executePrerequest (file:///home/dm/temp/39/k6/libs/shim/core.js:1187:203(89))

要使负载测试正常工作，我需要更改什么？

解决方法
我也无法使集合级别变量起作用。
相反，你应该改变
pm.collectionVariables.set
到
postman.setEnvironmentVariable
我注意到这会导致您的 Collection.baseUrl 和您的 Environment.baseUrl 发生冲突。
如果您分别上调环境和全局，那应该可以解决您的问题。
