We are developing a new site and have created some custom consumers for AMQP, however we are getting the error Error while checking if topic is synchronous during the setup:upgrade part of our deployment process.

I have identified that it looks to be redis causing this as removing the redis block from the env.php file resolves this. But I am not sure where to go after this.

  • double check the configuration of your queue topics. Are your topics sync or aysnc? Have you checked your log files for further information? – paj May 5 '20 at 19:48
  • Did you ever find out why? – Anna Völkl 2 days ago
