角4ユニバーサルthis.html.charCodeAtは関数ではありません

Question

私はAngular 4 Universal Starterを使用しており、このスターターにすべての角度2のコードを統合しています。すべて正常に動作していますが、端末ではこの奇妙なエラーが発生しています。わからないどのような問題が

ERROR TypeError: this.html.charCodeAt is not a function at Preprocessor.advance (/home/user/node/project/dist/server.js:152260:24) at Tokenizer._consume (/home/user/node/project/dist/server.js:45694:30) at Tokenizer.getNextToken (/home/user/node/project/dist/server.js:45652:23) at Parser._runParsingLoop (/home/user/node/project/dist/server.js:102429:36) at Parser.parseFragment (/home/user/node/project/dist/server.js:102384:10) at Object.parseFragment (/home/user/node/project/dist/server.js:55136:19) at Parse5DomAdapter.setInnerHTML (/home/user/node/project/dist/server.js:53609:49) at Parse5DomAdapter.setProperty (/home/user/node/project/dist/server.js:53250:18) at EmulatedEncapsulationServerRenderer2.DefaultServerRenderer2.setProperty (/home/user/node/project/dist/server.js:54766:94) at setElementProperty (/home/user/node/project/dist/server.js:9982:19)

あるserver.js

Preprocessor.prototype.advance = function() { 
    this.pos++; 

    if (this.pos > this.lastCharPos) { 
     if (!this.lastChunkWritten) 
      this.endOfChunkHit = true; 

     return $.EOF; 
    } 

    var cp = this.html.charCodeAt(this.pos); // Error Occurs here 

    //NOTE: any U+000A LINE FEED (LF) characters that immediately follow a U+000D CARRIAGE RETURN (CR) character 
    //must be ignored. 
    if (this.skipNextNewLine && cp === $.LINE_FEED) { 
     this.skipNextNewLine = false; 
     this._addGap(); 
     return this.advance(); 
    } 

    //NOTE: all U+000D CARRIAGE RETURN (CR) characters must be converted to U+000A LINE FEED (LF) characters 
    if (cp === $.CARRIAGE_RETURN) { 
     this.skipNextNewLine = true; 
     return $.LINE_FEED; 
    } 

    this.skipNextNewLine = false; 

    //OPTIMIZATION: first perform check if the code point in the allowed range that covers most common 
    //HTML input (e.g. ASCII codes) to avoid performance-cost operations for high-range code points. 
    return cp >= 0xD800 ? this._processHighRangeCodePoint(cp) : cp; 
}; 

this.html typeofにコードの下に起因する原因とITSは、「文字列」を返すが、直前には、オブジェクトの下に戻っているエラーです。以下は

ある

<div [innerHTML]="someHtml"></div> 

を使用したとき、私は同じエラーを経験した。しかし、私は次のように* ngIf = "someHtml" とそれを解決しましたこの

<div *ngIf="someHtml" [innerHTML]="someHtml"></div> 

これはあなたのためにもうまくいきますように！
