Hi all, Not sure if it's something I can control on my side but when I sign a module and install it on my local gateway it comes up as belonging to "Unknown Author". Did I miss something in the POM? Is this a config change on the IA side? Thanks for any help ---

I think it means both the vendor name in the module.xml file _and_ the CN of your signing cert are empty/missing. ---

Thanks Kevin. Turns out the signing cert had expired! All solved now 🙂
