Several /marry commands fail to work. My server is currently running on Spigot 1.12.2.

The relevant console output is shown below:

Is there any error when the plugin gets enabled?

Should be fixed with this build.

Thank you, everything works normally now! ^_^

Please try if this build solves the problem for you.
