这个错误是在GNOME桌面环境中使用键盘时发生的。可能是由于某种原因导致键盘脚本中的某个变量未定义而引起的。尝试重新启动GNOME桌面环境或重启计算机，以查看是否可以解决问题。如果问题仍然存在，请尝试在GNOME桌面环境中使用其他输入法或键盘布局，以查看是否有所改善。如果问题仍然存在，请查看您的系统日志以获取更多详细信息，并尝试在GNOME社区论坛或邮件列表中寻求帮助。

Error in callback for watcher "value": "TypeError: this.forest.selectedNodeIds.forEach is not a function"

根据引用\[1\]中的错误信息，错误是在watcher的回调函数中出现的，具体错误是"TypeError: Cannot read properties of undefined (reading 'apply')"。根据引用\[2\]中的报错信息，可能是由于箭头函数引起的this指向问题。然而，根据引用\[3\]中的建议，你可以检查后台接口返回的数据是否为null，如果是null的话，需要将其改为''。所以，根据你提供的错误信息，可能是在watcher的回调函数中使用了forEach方法，但是this.forest.selectedNodeIds不是一个函数。你可以检查一下this.forest.selectedNodeIds的值是否正确，并确保它是一个数组。

[Vue warn]: Error in callback for watcher "isShow": "TypeError: Cannot read properties of undefined (reading 'handleReset')"

引用中提到，在监视isShow属性的回调函数中，出现了一个TypeError: Cannot read properties of undefined (reading 'handleReset')的错误。这个错误提示说明回调函数中尝试读取一个未定义的属性'handleReset'，导致了错误的发生。通常这种错误是由于函数名拼写错误或者未正确定义函数引起的。可以通过检查函数名拼写是否正确以及确保函数已正确定义来解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
