Openlayers 6.4.3:未捕获类型错误：无法分配给只读属性'；0'；字符串'；bo&x27；

当调整

Map

对象的父对象

div

的大小时，会导致下面的堆栈跟踪。我正在尝试在ExtJS 6.2应用程序中使用

    transform.js:117 Uncaught TypeError: Cannot assign to read only property '0' of string 'bo'
        at Tt (transform.js:117)

Openlayer 4中没有此错误。有什么解决办法吗？

我在创建覆盖时出现了这个错误。这是因为我在启动覆盖时使用了position关键字而不是

positioning

首先确保使用了正确的关键字，然后确保传递的是有效的坐标值或未定义的值
