Type: Dedicated Server (map_server.txt)

Looks like the error is XaeroMinimap trying to access client-side code from the dedicated server. Why does it need to be installed on the server? If it doesn’t, uninstall it and try again.

When providing error logs or long files, please use pastebin, a similar service or a [spoiler]Hidden Text[/spoiler]

Looks like you’re running an old Sponge build. Try updating it first please. The name is a bit off too:

sponge-1.8-5121-2.1DEV-726.jar.jar

It should be Sponge-1.8-1521-2.1DEV-726. Please note that the number i marked in bold is the recommended Forge build for this SpongeForge. You should match the versions whenever possible.

Get the newest SpongeForge build here: spongeforge and try again. If your problem still persists, have a look at this: https://docs.spongepowered.org/en/server/spongineer/debugging.html and go through the Checklist.
