[ERROR] worker: failed to dequeue evaluation

Hello good people,
I am currently building a nomad server cluster consisting of 3 nodes. I have successfully built the nomad cluster and made Node 3 the cluster leader. but when I use the command “sudo systemctl status nomad” I get this error (attached image)

error message :
