Hello, I'm using trying to use the nx (neo4j data importer) app from the neo4j Desktop to connect to my local neo4j database (5.18.1) localhost:7687 . Importer show "An recoverable error has occurred "Reload application". Reload does not do anything. I can access and use the neo4j data importer using my browser. I would like to understand why launching the neo4j data importer from the desktop is not working

Hi, According to https://neo4j-aura.canny.io/feature-requests/p/enable-triggers , we have now the possibility to use call apoc trigger add in Aura, however I get a message asking to enable it in apoc.conf. How can I do it? Thanks

I have a db on cloud, how to export data into rdf from cloud ?

I don't know if this is how it's supposed to be but I have read online that the captions for nodes can be changed to a different property however I cannot find any way to do this from my neo4j workspace browser gui. Any ideas? (I want to swap the caption of User nodes to a UUID rather than name)

Finding a single node, even with the full indexed label, takes > 15 seconds to return.
