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 ?

How to start 3 instance cluster in neo4j. Docs not working

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.

As I was just getting started with Aura trying to get my Spring Boot app up and running, I discovered that the Connect - Spring Boot page could use some more info such as the versions of Spring Boot Data & Neo4j OGM that work properly. In my case, my app was throwing a ClassNotFoundException: org.neo4j.driver.util.BookmarkUtil when I attempted to access the database. I was stumped until I discovered this page: https://medium.com/neo4j/using-neo4j-aura-from-java-and-spring-boot-f1c1684894f8 It turned out my version of Neo4j OGM was slightly out of date (by just a couple of patch versions!). I upgraded to the versions mentioned in the article and the problem went away. Others might be saved some trouble if the Connect - Spring Boot page mentioned the compatible Spring Data & Neo4j OGM versions, or perhaps included a link to the above mentioned article.

We need some information on the Bloom pricing after 31/01/2021
