Restart required to access a newly created connection

Hi,

 

whenever I create a new connection (via the RM Studio or by a program that sends a corresponding POST request to the server) and run a process that uses this connection right afterwards, I cannot access it. However, if I restart the server and run the same process again, everything works. I tried this with the Twitter connection (for reverence) and the SPARQL Endpoint Connection (main use case) of the LOD Extension [0].

Before I continue debugging I would like to ask whether there is a technical restriction which forces this restart or whether I'm just missing a certain step or most likely do something wrong here. I'm using the RapidMiner Server 7.2.0.

 

Thanks and best regards,

Patrick
