一个致命的JavaScript错误？

Question

我正在尝试解决当我在phpMyAdmin中将规范化应用于我的表时如何修复此错误。当我尝试完成规范化过程的3NF时，这只会弹出屏幕的底部。

下面是我看到的错误代码的片段，但我似乎无法弄清楚如何解决问题。我也试过几个浏览器，似乎都给出了同样的问题。

有人也发布了一个关于此错误的类似问题，但他们的报告代码完全不同。我感谢任何可以提供的帮助！这是从phpMyAdmin UI

由于我遇到类似的JavaScript错误，我相信您实际上发现了我在https://github.com/phpmyadmin/phpmyadmin/issues/12927报告的phpMyAdmin错误
