Hey @christianbader thank you :-) I have the feeling you are not on version 4.2.0 of Elastica bridge. However, if we change this, we should change it to something like this. What do you think?

The output would then look like this:

+------------------- Cluster ----+---------------+
| Key                            | Value         |
+--------------------------------+---------------+
| host                           |               |
| port                           |               |
| path                           |               |
| url                            |               |
| connections.0.host             | elasticsearch |
| connections.0.port             | 9200          |
| connections.0.transport_config | http_client   |
| roundRobin                     |               |
| retryOnConflict                | 0             |
| username                       |               |
| password                       |               |
| connectionStrategy             | Simple        |
+--------------------------------+---------------+
