Connect to Heroku redis from a nestjs app

Question

I am hosting my nestjs application on Heroku and trying to use "Heroku redis" add-on with it.

In the app.module.ts I am importing RedisModule as follows:

@Module({
 imports: [
  RedisModule.register({ host: process.env.REDIS_URL }) 
 ]
})

After configuring Heroku-redis add-on, it added REDIS_URL under config vars in Heroku, however, when I deploy and run the application, I get the following error message:

2020-06-11T09:00:48.690255+00:00 app[web.1]: [ioredis] Unhandled error event: Error: getaddrinfo ENOTFOUND redis://h:abc@ec2-52-51-206-63.eu-west-1.compute.amazonaws.com:16719

(I've replaced the real url value with a sample one to illustrate the problem)

I can't seem to find

Answer 1

RedisModule.register({ url: process.env.REDIS_URL })
