在未使用的方法中取消注释部分代码后，Monaco Web 编辑器无法正常工作

Question

我尝试在 Monaco 网络编辑器上添加建议，但遇到了一个非常奇怪的问题。考虑班级：

import { ExpressionContext } from "../ANTLR/ExpressionsParserGrammarParser";

import * as monaco from "monaco-editor-core";
import { ILanguageError } from "../todo-lang/ILanguageError";
import { calcFormatted } from "../todo-lang/FormatterVisitor";
import { parseAndGetASTRoot, parseAndGetSyntaxErrors } from "../todo-lang/parser";


export default class TodoLangLanguageService {
    validate(code: string): ILanguageError[] {
        const syntaxErrors: ILanguageError[] = parseAndGetSyntaxErrors(code);
        const ast: ExpressionContext = parseAndGetASTRoot(code);
        return syntaxErrors;//.concat(checkSemanticRules(ast));
    }
    format(code: string): string {
        return calcFormatted(code).value
    }

    autoSuggest(code: string, line: number, charPosInLine: number): monaco.languages.CompletionList {

        const syntaxErrors: ILanguageError[] = parseAndGetSyntaxErrors(code);
        let completeonItems: Array<monaco.languages.CompletionItem> = syntaxErrors.filter(err => err.startLineNumber == line && err.startColumn == charPosInLine).map(e => {
            let ci: monaco.languages.CompletionItem = {

                label: e.message,
                /**
                 * The kind of this completion item. Based on the kind
                 * an icon is chosen by the editor.
                 */
                kind: monaco.languages.CompletionItemKind.Field,

                insertText: e.message,
                range: {
                    /**
                     * Line number on which the range starts (starts at 1).
                    */
                    startLineNumber: e.startLineNumber,
                    /**
                     * Column on which the range starts in line `startLineNumber` (starts at 1).
                     */
                    startColumn: e.startColumn,
                    /**
                     * Line number on which the range ends.
                     */
                    endLineNumber: e.endLineNumber,
                    /**
                     * Column on which the range ends in line `endLineNumber`.
                     */
                    endColumn: e.endColumn
                }
            }
            return ci;
        })

        let ci:monaco.languages.CompletionList={
            suggestions:completeonItems
        }
        return ci;
    }
}

源代码中没有使用“autosuggest”方法（我已经注释掉了）。问题是 Monaco Web Editor 不处理语言功能——语法着色、格式化和错误突出显示。

但是如果我按照下面的方式更改自动建议方法，一切正常，当然没有建议：

 autoSuggest(code: string, line: number, charPosInLine: number): monaco.languages.CompletionList {

        const syntaxErrors: ILanguageError[] = parseAndGetSyntaxErrors(code);
        
        let ci:monaco.languages.CompletionList={
            suggestions:[]
        }
        

    return ci;
}

我的 package.json 如下：

{
  "name": "todolangeditor",
  "version": "1.0.0",
  "description": "TodoLang editor",
  "scripts": {
    "start": "webpack-dev-server --hot --open",

    "webpack": "^4.29.6",
    "webpack-cli": "^3.3.0",
    "webpack-dev-server": "^3.2.1"
  }
}

当我运行 npm install 时，我有以下日志，有几个警告但没有错误：
