我使用Angular 8，Angular Universe，ngx-bootstrap设置服务器端渲染，但出现错误
ERROR ReferenceError：未定义文档 在ModalContainerComponent.ngOnInit（/Users/user/project/dist/server.js:243925:9） 在checkAndUpdateDirectiveInline（/Users/user/project/dist/server.js:23530:19） 在checkAndUpdateNodeInline（/Users/user/project/dist/server.js:31788:20） 在checkAndUpdateNode（/Users/user/project/dist/server.js:31750:16） 在prodCheckAndUpdateNode（/Users/user/project/dist/server.js:32291:5） 在Object.updateDirectives（/Users/user/project/dist/server.js:137344:457） 在Object.updateDirectives（/Users/user/project//server.js:32079:72） 在Object.checkAndUpdateView（/Users/user/project//server.js:31732:14） 在ViewRef_.detectChanges（/Users/user/project//server.js:23119:22） 在ComponentLoader.show（/Users/user/project//server.js:241722:50）
我尝试在服务器文件中使用多米诺骨牌，但没有帮助
