无法创建数据源\“ bank-server \”：无法初始化连接器\“ rest \”：无法读取未定义的属性'root'

Question

我在尝试执行作业时遇到错误。

import * as loopback from 'loopback';
import * as boot from 'loopback-boot';
import {JobEntrypoint} from '../utils/jobs/JobEntrypoint';
import {WinstonLoggerFactory} from '../utils/logging/WinstonLoggerFactory';
import {LoggingCategoryType} from '../../shared/all/types/LoggingCategoryType';
import {IConfig} from './IConfig';
import * as config from './config';
import {HashLinkedLogFactory} from '../../shared/all-servers/logging/HashLinkedLogFactory';
import {debug} from "util";

HashLinkedLogFactory.initializeInstance((config as IConfig).signedInitialisationVector.initialisationVector);

const app: any = module.exports = loopback();
const logger = new WinstonLoggerFactory().getBootLogger();

console.log('--> server');
// Bootstrap the application, configure models, datasources and middleware.
// Sub-apps like REST API are mounted via boot scripts.


boot(app, __dirname, async (bootError) => {
  console.log('--> server   1');
  if (bootError) {
    logger.error('Error during boot', {
      bootError: bootError,
      category: LoggingCategoryType.Server
    });
    console.log('--> server    2');
    process.exit(1);
  }

  const jobEntrypoint = new JobEntrypoint(app, logger);

  if (jobEntrypoint.hasJobToExecute()) {
    console.log('--> server   3');
    try {
      await jobEntrypoint.executeJob();
      logger.info('done!', {category: LoggingCategoryType.Jobs});

      process.exit(0);
    } catch (error) {
      logger.error('failed!', {error: error, category: LoggingCategoryType.Jobs});

      process.exit(1);
    }
  } else {
    throw new Error('No job to execute (at least one is expected)');
  }
});

当我调试时，我了解到引导脚本正在加载，并且引发了一个错误，即它无法“创建数据源并且无法连接其余初始化程序，然后无法读取未定义的属性'root'。”

TypeError: Cannot create data source "bank-server": Cannot initialize connector "rest": Cannot read property 'root' of undefined。

有人遇到此错误吗？

感谢您的评论。解决了datasources.local.js中的变量名称不匹配。改正变量名称后，它已得到修复。
