export a graph from graphcatalog to csv

[aprilsong0323]

I am using the CALL gds.beta.graph.export.csv function, and it gives this error 

Failed to invoke procedure `gds.beta.graph.export.csv`: Caused by: java.nio.file.FileSystemException: /": Read-only file system

I have used the same folder for apoc.export.csv.all and it has no problem, which indicates that neo4j does have writing permission to that folder.

Please help.

Did you configure the location? 

The gds.export.location parameter must be configured for this feature.
