I want to use the metabolism command as a reward with ServerRewards but calling it via that plugin or directly from RCON produces the following error:

Well yes, from rcon you don't have a player object containing permissions, so it will fail the permission check.
I'll have a look and add an ```rcon  or permission check.```

Merged post

Should work with v1.5.4

Fixed! Thank you so much for this and especially how quickly you did it. Donated :)

Thank you for the generosity. :)
