Failed to invoke procedure `gds.alpha.leiden.write`: Caused by: java.lang.IllegalStateException: No

Hi,

I encoutered this error when trying to run

Neo.ClientError.Procedure.ProcedureCallFailed
Failed to invoke procedure `gds.alpha.leiden.write`: Caused by: java.lang.IllegalStateException: No more running tasks

It was working fine yesterday. I don't get what it means: no running task? Other 
gds functions are working fine. 

Has everyone has this before?

Thank you
