Hello Adam,
I think you need to execute two requests, the 1st is to add a dynamic
property to RouteOnAttribute, and the 2nd is to create a connection
from RouteOnAttribute.
Here is an example for the 1st request adding a dynamic property using
cURL command:
curl -i -H 'Content-Type: application/json' -XPUT -d
'{"component":{"id":"51bf89dc-015c-1000-6493-68ecce3a36d9","name":"RouteOnAttribute","config":{"properties":{"filter":"${someAttribute:contains('someValue')}"}}},"revision":{"clientId":"51bf55c6-015c-1000-c259-19995ecde81f","version":4}}'
http://localhost:8080/nifi-api/processors/51bf89dc-015c-1000-6493-68ecce3a36d9
After that, I was able to add a connection by 2nd request as follows,
the key would be specifying "selectedRelationshipls" array with the
property name you added to RouteOnAttribute:
curl -i -H 'Content-Type: application/json' -XPOST -d
'{"revision":{"clientId":"51bf55c6-015c-1000-c259-19995ecde81f","version":0},"component":{"name":"","source":{"id":"51bf89dc-015c-1000-6493-68ecce3a36d9","groupId":"51bf0c82-015c-1000-aac1-7b724a24b1c4","type":"PROCESSOR"},"destination":{"id":"51c05d2c-015c-1000-69f5-3d972a6959a4","groupId":"51bf0c82-015c-1000-aac1-7b724a24b1c4","type":"PROCESSOR"},"selectedRelationships":["filter"],"flowFileExpiration":"0
sec","backPressureDataSizeThreshold":"1
GB","backPressureObjectThreshold":"10000","bends":[],"prioritizers":[]}}'

Thanks,
