Description

We've got this:

ATTENTION: The pipeline contains no upstream handlers; discarding: [id: 0x1f79354a] OPEN
ATTENTION: The pipeline contains no upstream handlers; discarding: [id: 0x1f79354a] BOUND: 0.0.0.0/0.0.0.0:37250
ATTENTION: The pipeline contains no upstream handlers; discarding: [id: 0x1f79354a, 0.0.0.0/0.0.0.0:37250 => /226.1.1.3:60100] CONNECTED: /226.1.1.3:60100

ATTENTION: The pipeline contains no upstream handlers; discarding: [id: 0x1f79354a, 0.0.0.0/0.0.0.0:37250 :> /226.1.1.3:60100] UNBOUND

We can fix this by adding an upstream handler that discards the message without printing them.
