在 prod 服务器 (Azure) 上引发语法错误，但不是在本地 - 无法找出原因

Question

让我先说一下，我知道这极有可能是脚本中的标准基本语法错误，但在我的一生中我找不到它。

这是 chrome 检查控制台中抛出的错误 -

    at c (jsbundle?v=hZeIDp2ez9Xzj2b2pzhcILhAY4fxF_YgY7wSOowNqpk1:8)

虽然错误不在所述文件（社区详细信息）中，但在检查源代码时，它位于 JS 文件中，我标记了似乎在 function 末尾附近引发语法错误的内容 -

缩小有时可能会产生语法不正确的 output。 如果禁用它，请检查问题是否消失。 如果是这样，请尝试将 Minification 库更新为较新的版本，或者甚至尝试将其替换为替代方案。
