最佳答案
将协议(protocol)版本设置为2可以解决大多数情况下的错误，或者您可以选择将redis-client版本升级到6以上。
redis 协议(protocol)版本可以设置为1 或 2。
协议(protocol)版本2是Redis 6.0中引入的增强协议(protocol)版本。
您可以将如下所示的协议(protocol)添加到 redis 配置中，
Sidekiq.configure_client do |config|
config.redis = {
url: Rails.application.credentials.config[:REDIS_URL],
protocol: 2,
}
end
