我从GitLab CI收到此错误。但是在本地开发人员上运行得很好。我尝试了几种方法来将Redis端口转换/解析为数字，还用console.log('Redis port type: ',typeof(REDIS_PORT)检查，返回number。

这是CI的完整日志

$ npm run test:ci

这是config.ts文件，用于获取环境变量。

// config.ts

export const {
  // ... bunch of others
  REDIS_PORT = 6379 
} = process.env

// Redis options for subscription pubsub,bull queue and ioredis
export const redisOptions = {
  host: REDIS_HOST,// Unary operator `+` to convert number
  port: +REDIS_PORT,// port: Number(REDIS_PORT),<- this does not work either
  password: REDIS_PASSWORD,}

我将ioredis用于Apollo GraphQL缓存和Bull队列。

// lib/redis.ts

// Tried adding redis connection options here,but didn't work
const redisClient = new Redis(redisOptions)

redisClient.on('connect',() => {
  logger.info('Redis client connected')
})

redisClient.on('error',err => {
  // I believe that the error is coming from here!
  logger.error(`Redis client error: ${err}`)
  process.exit(1)
})

export default redisClient

公牛队排队发送欢迎电子邮件

// auth/queue.ts

const emailQueue = {
  welcomeEmailQueue: new Queue('email',{ redis: redisOptions }),}

// ... other stuffs

请帮助我。我在做什么错了？
