[img]I have setup a NATURAL RPC Server running on mainframe (VSE) with Broker also on mainframe. When I try to connect and extract IDL I get a garbage screen. No error, no library listings. I can ping Broker from my PC. I have added 4 libs to Steplib for SYSTEM: SYSIDL, SYSRPC, SYSEXT, SYSLIBS. What am I missing? Thanks Popup box says IDL Extractor for NATURAL as title. Body has a RED X and text "For input string “xxxx”. where xxxx are some weird characters. ![error message.jpg](https://global.discourse-cdn.com/techcommunity/original/2X/0/030402b060ff17b2c57f60d33a2d6965b36643d5.jpeg) ---

Hi MIke, maybe you forgot to enable conversion for this service in the attribute file. ---

Hi, If you have a supported Natural version, you do not need to configure STEPLIBs. To configure steplibs for IDL extraction is a really old thing. It was kicked out in EntireX 15-20 years ago. Maybe your setup causes the problem. Try a simple Natural RPC Server. As Rolf mentioned, keep an eye on conversion. Regards Bernhard ---
