使用nestjs库@nestjs/elasticsearch，@elastic/elasticsearch

imports: [ConfigModule.forRoot( {
    validationSchema,
    validationOptions: {
      abortEarly: true,
    }
  }),
    SearchModule,
    UserSkillsModule
  ],
  controllers: [SearchController, UserSkillsController],
  providers: [],
})
export class AppModule {}

search.module.ts搜索模块

@Module({
    imports: [ConfigModule, ElasticsearchModule.registerAsync({
    imports:[ConfigModule],
    useFactory: async(configService: ConfigService) => ({
      node: configService.get('ELASTICSEARCH_HOST')
    }),
    inject: [ConfigService],
  }),],
  providers: [SearchService],
  exports: [SearchService, ElasticsearchModule]
})
export class SearchModule {}

.环境

ELASTICSEARCH_HOST= ((I have specified the url correctly))

搜索服务.ts

import { Injectable, InternalServerErrorException, Logger } from '@nestjs/common';
import { ElasticsearchService } from '@nestjs/elasticsearch';
import { UserSkills } from '../user-skills/dto/userSkill.interface';

@Injectable()
export class SearchService {
  constructor(
   private elasticsearchService: ElasticsearchService
  ){}
private logger = new Logger('SearchService');
 async addUserSkills(userPublicId: string, companyPublicId: string, skills: UserSkills[]): Promise<any> {
    const tempObj = {};
    tempObj[userPublicId] = skills;
    console.log('TEMP OBJECT ---- ', tempObj);
    const document = {
      index: companyPublicId,
      body: tempObj
    }
    let result;
    try {
      result = await this.elasticsearchService.index(document);
    } catch(error) {
      this.logger.verbose(`Error creating an index ---- ${error}`);
      throw new InternalServerErrorException(`Error creating index ---- ${error}`);
    }
    return result;
   }

这将引发以下错误：

[Nest] 50872   - 09/17/2020, 9:29:21 AM   [Error: Error creating index ---- ResponseError: index_not_found_exception]

我不确定我从文件中遗漏了什么。请帮帮我。谢谢您。
