Question 121360 in Redis Question posted in
The official documentation can be found here.

Why is @nestjs/bull not able to connect to Heroku Redis?

This works for local redis-server

BullModule.forRoot({
    redis: {
        host: "localhost",
        port: 6379,
        db: 0,
        password: ""
    }
})

But if I use the DataStore Credentials on Heroku Redis, the bull board does not load and Heroku Logs gives an H12 error.

How can I get the BullModule to properly connect to Heroku Data for Redis?

Thanks!

    I suggest trying

    BullModule.forRoot({
    redis: "<redisurl given by heroku in env variable>"
})

    This fixed the issue for me.

    You must specify the location of where redis is accessible. localhost:6379 is the default for running redis locally, but to deploy an application that uses Redis to Heroku, you will need to add the Connecting to Heroku Data for Redis add-on. Then, you’ll need to pass the location of your Redis service via process.env.REDIS_URL to the BullModule.forRoot() constructor.

    Be aware that encountering TLS issues in connecting to Redis like this are common. When I tried connecting using the format from PedroPovedaQ’s answer, I ran into one.
    There’s a discusson on that here.
