Pseudo-terminal won't be allocated because stdin are not a terminal

Encountered an SSH issue, executing the ssh command times "pseudo-terminal won't be allocated because stdin are not a terminal"

Scripts run directly on the server although this error is also reported, the port link is OK, but the script uses Jenkins run when the port link fails.

... tunnelargs = ["ssh", "T", "-ostricthostkeychecking=no",
"-ouserknownhostsfile=/dev/null", "I",
Sshmanager.privatekey, "-L",
STR (self.tunnellocalport) + ":" + Host + ":" + str (ssh_default_port),
Self.gatewayuser + "@" + Self.gateway]
Process = Popen (Tunnelargs, Stdout=pipe)
...

Rc:stdin is not a terminal, but why executing scripts on the server is still successful, and the difference between Jenkins execution is not clear.

Solution: Add parameter-t-t
