unable to grant a user permissions to a custom topic via web ui

[dch]

• RabbitMQ version 3.8.3 + admin plugins from same version
• Erlang version 21.3.8.14

If your issue involves RabbitMQ management UI or HTTP API, please also provide the following:

• Browser and its version: Firefox 76
• What management UI page was used (if applicable) http://localhost:15672/#/users/:some_user
• How the HTTP API requests performed can be reproduced with curl

• when logged in as admin to the std admin console
• and selecting a user
• it is not possible to add topic permissions to a custom non-default exchange
• only the default (AMQP default) and amq.* exchanges appear in the UI.

NB the actual task was to add write permissions to a given topic exchange for a specific vhost, to create a "write-only" user to publish to a routing key similar to syslog.<hostname>. On a local rabbitmq system I would probably run:

$ rabbitmqctl set_topic_permissions -p vhost rsyslog api.topic "^api.topic" "^$"

I cannot reproduce with 3.8.4-rc.3 but since you have mentioned a "specific vhost", this is likely a duplicate of #806.

whoops - definitely a duplicate
