Angular 12.1.1 和 ngx-extended-pdf-viewer 9.0.5 在我们对 12.1.1 版本的最新更新中，我们遇到了一个问题： ngx-extended-pdf-viewer 下面是代码片段：

包.json

    "dependencies": {
        "@angular/animations": "12.1.1",
        "@angular/common": "12.1.1",
        "@angular/compiler": "12.1.1",
        "@angular/core": "12.1.1",
        "@angular/forms": "12.1.1",
        "@angular/material": "12.1.1",
        "@angular/material-moment-adapter": "12.1.1",
        "@angular/platform-browser": "12.1.1",
        "@angular/platform-browser-dynamic": "12.1.1",
        "@angular/router": "12.1.1",
         etc...
        "ngx-extended-pdf-viewer": "9.0.5",
          etc...
      },
    
    
    ****Angular.json****

  "sourceMap": true,
    "assets": [
      "src/favicon.ico",
      "src/assets" ,
      {
        "glob": "**/*",
        "input": "node_modules/ngx-extended-pdf-viewer/assets",
        "output": "/assets/"
      },
      {
        "glob": "**/*.md",
        "input": "src/app/",
        "output": "/assets"
      } ,
      {
        "glob": "changelog.md",
        "input": "node_modules/ngx-extended-pdf-viewer/",
        "output": "/assets/changelog/"
      } 
                         
    **HTML**


   <div class="col-12 center-alignStd" style="padding-left: 2px; padding-right: 2px;">
            <ngx-extended-pdf-viewer
                [base64Src]="documentUrl"
                [useBrowserLocale]="useBrowserLocale" 
                [textLayer]="textLayer" 
                [logLevel]="0" 
                height="'60vh'"> 
            </ngx-extended-pdf-viewer>                       
       </div>

打字稿

       ngOnInit() { 
// this.data.url contains a hardcoded sample
// import { pdfBase64 }         from '@shared/pdfBase64';
            let vm =  this;
            if (this.data.TypeOfData == 'pdf')
            {
                vm.pdfParam = true;
                vm.documentUrl = this.data.url;
                
            } else {
                this.pdfParam = false;
                vm.documentUrl = this.data.url;
            }  
        }

当我们执行代码时，没有编译或运行时错误。是否有人对如何调试此代码有任何想法。在以前的版本中，这有效。
