Yes, indeed the error message is empty. After some investigation IMHO it looks like there is no easy solution. LISA functions return an error code but I don’t see a way to return the related message. wpeframework does fill in a message for error codes that it knows itself (the common error codes): https://github.com/rdkcentral/Thunder/blob/89968f149299ff5647cc4a4ab9d4f948c858ebff/Source/WPEFramework/PluginServer.h#L1559
