Plugin Help 1.13.2 Server Plugin Errors

Im rather new to this kind of stuff so im not the best! the past several days ive been setting up a server and installing numerous plugins. I recently installed the skywars plugin, and began setting it up. I went to do the "sws save" command to save the arena i had edited and it threw an internal error at me in the chat. I check the servers console and it gives me this error.
