类型错误：无法读取 null 的属性（读取“split”）

Question

我有一个角度应用程序，当我尝试访问它时，它向我抛出此错误。

TypeError: Cannot read properties of null (reading 'split')
    at required (/Users/.../node_modules/requires-port/index.js:13:23)
    at Object.common.setupOutgoing (/Users/.../node_modules/http-proxy/lib/http-proxy/common.js:101:7)
    at Array.stream (/Users/.../node_modules/http-proxy/lib/http-proxy/passes/web-incoming.js:127:14)
    at ProxyServer.<anonymous> (/Users/.../node_modules/http-proxy/lib/http-proxy/index.js:81:21)
    at HttpProxyMiddleware.middleware (.../node_modules/http-proxy-middleware/dist/http-proxy-middleware.js:22:32)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

当我尝试在 Mac OS Catalina 上运行该应用程序时，会发生这种情况。在 Linux ubuntu 上运行时，该应用程序可以正常运行。 这就是我的环境。

正如@Belouccio 所指出的，“target”中的链接应包含“http”

{
  "/api/*": {
    "target": "https://{{link}}",
    ...

  }
}
