由於某種原因，我的NextJS（託管在Vercel上）的API呼叫在更新軟體包或重新調整yarn.lock後在生產環境中失敗。每個API呼叫（甚至一個簡單的hello world）都會傳回類似索引檔的HTML。導致此問題的軟體包是更新Mantine，這是一個客戶端UI庫。然而，我注意到即使我將所有軟體包鎖定到特定版本號，並且yarn.lock根本不改變，這個問題現在也會發生。
這是我在Vercel日誌中收到的錯誤，但它並沒有真正幫助，因為Memberstack是客戶端包，負責管理我們的身份驗證。而且我只在客戶端頁面上使用這個套件。

我嘗試刪除yarn.lock並重新安裝所有軟體包，但這也會導致生產環境中的API呼叫出錯。唯一有效的方法是直接複製先前在生產環境中工作的相同yarn.lock文件，並在部署時使用它。
所以基本上，我不能碰yarn.lock文件，否則會破壞生產環境，或只能觸碰某些軟體包。
我正在努力弄清楚我安裝的軟體包是否有問題，當安裝/升級軟體包時，是否需要在yarn上執行某些操作？或者這是NextJS與我使用的某些軟體包之間的相容性問題？
看起來像是
/var/task/node_modules/@memberstack/dom/lib/methods/index.js:45:5正試圖存取window#，然而由於NextJS進行了伺服器端渲染(SSR)，它很可能是未定義的。我建議在呼叫 window 之前加上
typeof window === undefined，或使用 NextJS 的 dynamic package 並在匯入 memberstack 時停用 SSR。
