Redis-client for Sidekiq 7 on Heroku

I am using Sidekiq on an app hosted on HerokuI was using the redis gem.

When I upgrade to sidekiq 7 which uses redis-client instead of redis I get this error:

redis-client requires Redis 6+ with HELLO command available

The Redis instance I have on Heroku is on the version 6.2.6 (so Redis 6+)

Attached my redis.rb file (in initializers). I tried replacing Redis with RedisClient but I still get the error in both cases. Which means that it is when the Sidekiq code is internally using redis-client the error is happening

Any thoughts or ideas would be highly appreciated 🙏🏼 Thanks in advance!

I was expecting this to work as my Redis instance is on a 6+ version
