Cross-server teleport from console throwing an error

[Dagrond]

I have huskHomes on spigot setup (via redis) with following structure:

Player "Dagrond" on server A
Player "Dnorgad" on server B.

When I type "tp Dnorgad Dagrond" on server's A console, I get following error:

It is not happening when typing reverse, eg. "tp Dagrond Dnorgad".
Same error happens When I have warp/spawn on server A and try to teleport player from server B to that warp using /warp.

It seems like an error because I can use ingame /tphere command to teleport player from server B to my location on server A.
Also, using ingame /tp Dnorgad Dagrond command is working fine... Which is basically doing exact same thing lol.
But using ingame /spawn Dnorgad when player is not on that server is also causing this error. Unless, player is on same server.

This error should no longer be thrown and a friendly error displayed instead

Cross-server teleportation requires a player online on the server the command was executed on
