Makara latest + ruby 3: `NoMethodError: undefined method 'provide' for nil:NilClass`

[cr0mbly]

Hey guys thanks for all the hard work, I'm wanting to upgrade a rails app to ruby 3 but am failing on makara:

I've tried on both rails 3.0/3.2 with both makara 5.1 and 0.6.0.pre:

database.yml config is:

development: &development
  adapter: mysql2_makara
  encoding: utf8mb4
  database: <redacted>
  pool: 5
  username: <redacted>
  password: <redacted>
  host: <redacted>
  port: 3306
  timeout: 5000
  strict: false
  makara:
    blacklist_duration: 5
    primary_ttl: 5
    primary_strategy: round_robin
    sticky: true
    connections:
      - role: primary
        host: <redacted>
      - role: replica
        host: <redacted>

This fails on first boot running

bundle exec rake db:abort_if_pending_migrations

but figure it'll be on anything attempting to first connect up to the DB via makara

@cr0mbly Did you solve this? Hitting the same error.

[cr0mbly]

@wjessop Nope we ended up just removing makara in favor of rails implementation. It actually works fairly well as of 6.1 If you can I'd switch over to that.

[lloydwatkin]

@wjessop we got hit with the same, and Makara seems broken with ActiveRecord7.1+, so we created @olioex/janus-ar to solve the problem

Thanks @lloydwatkin, I'll check it out. I'll likely try the baked in Rails feature though.
