我正在尝试使用同构网格，为了加载它我必须使用 FileLoader.load() 方法。
isc.FileLoader.load(() => {
builder(element,datasource);
}, {target: element});
但是每当我使用它来加载网格（有效）时，它会破坏我的角度路由并且我会收到以下错误：
src_app_apartados_contactos_contactos_module_ts.js:2 ERROR Error: Uncaught (in promise): TypeError: Cannot read properties of null (reading 'children')
TypeError: Cannot read properties of null (reading 'children')

额外信息：我遵循本指南：https://smartclient.com/smartclient-release/isomorphic/system/reference/?id=group..backgroundDownload
我试过做很多事情，改变路由选项，摆脱延迟加载，尝试不同的配置，问题是 100% FileLoader。
