when using Pipeline item can't start the executor on the slave nor on executor on master
tried the hello world sample and it didn't run.

Started by user admin
[Pipeline] node
Still waiting to schedule task
Waiting for next available executor on "any slave"
[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: Queue task was cancelled
Finished: FAILURE

The executors are available and there is no problem of disk space

P.S
the regular jobs works great on the slave
