[Screen Shot 2022-03-02 at 1.32.03 PM] I keep getting this Redis Error when I try to migrate my db. This discourse docker install. Please help.

[image] natasha_selvidge: /Users/natashaselvidge/discourse/vendor/bundle/ruby/2.6.0/gems/redis-4.6.0 [image] natasha_selvidge: Redis::CommandError: ERR unknown command synchronize, with args beginning with: Looks like you manually update the Redis gem on your dev environment from 4.5.1 to 4.6.0. Discourse doesn’t work with that gem version, so you need to revert back to the version we use on the Gemfile.lock file. We are working on eventually moving to redis-rb 4.6.0, but that is a lot of work: https://github.com/discourse/discourse/pull/15811

Do you have a 2 container install or redis hosted elsewhere? Do you have redis 6.2?

This is my Redis version 6.2.6 and I only have one redis container in my docker and then a few discourse_dev containers too.

I have requested help on the sidekiq github too.

Ohhhh okay, thank you so much! I will try that :folded_hands:t3:

[image] Falco: 4.5.1 Update For anyone who may need this in the future :hugs: Thank you so much that fixed it! I updated my discourse, but the version wasn’t specified on the gem file. I added the version number to the end like this: gem ‘redis’, “~> 4.5.1”

We specify it at the Gemfile.lock: Gemfile.lock main racc (~> 1.4) nokogiri (1.19.3-arm-linux-musl) racc (~> 1.4) nokogiri (1.19.3-arm64-darwin) racc (~> 1.4) nokogiri (1.19.3-x86_64-darwin) racc (~> 1.4) nokogiri (1.19.3-x86_64-linux-gnu) racc (~> 1.4) nokogiri (1.19.3-x86_64-linux-musl) racc (~> 1.4) oauth (1.1.3) base64 (~> 0.1) oauth-tty (~> 1.0, >= 1.0.6) snaky_hash (~> 2.0) version_gem (~> 1.1, >= 1.1.9) oauth-tty (1.0.6) version_gem (~> 1.1, >= 1.1.9) oauth2 (1.4.11) faraday (>= 0.17.3, = 1.0, < 3.0)

I think because I deleted my Gemfile lock and bundled. Then I was talking to the redis and sidekiq issues guys on Github and they were telling me I had to be on the updated version. Thanks again!
