我正在从头开始编写一个 cljs 库（即没有 leiningen 模板）。使用lein figwheel，Figwheel 成功地将我的 cljs 编译为 JS，但由于控制台中出现以下三个错误，因此无法完全连接到我的应用程序：

Uncaught TypeError: Cannot read property 'call' of undefined
    at utils.cljs?rel=1627878774806:73

Uncaught TypeError: Cannot read property 'call' of undefined

    at client.cljs?rel=1628044052054:473

这是我的 core.cljs：

(ns cljs-spotify-sdk.core)

(defn load-sdk []
  (let [script-id "spotifySDK"]
    (when-not (. js/document (getElementById script-id))
      (let [script (. js/document (createElement "script"))]
        (-> script (.-id) (set! script-id))
        (-> script (.-type) (set! "text/javascript"))
        (-> script (.-async) (set! true))
        (-> script (.-src) (set! "//sdk.scdn.co/spotify-player.js"))
        (let [first-js (-> js/document (.getElementsByTagName "script") (aget 0))
              parent (.-parentNode first-js)]
          (.insertBefore parent script first-js)))))
  (.log js/console "SDK script inserted"))

如何解决这些错误？
