Redis-cli cannot perform --pipe with -c

[Heermosi]

Environment: CentOS 7.5 docker container
SoftVersion: Redis 5.0.5
Deployment: Redis Cluster with 3 masters and 3 slaves
Problem:

When I import data using
cat script | redis-cli -h localhost -p 7000 -c
it was all OK

When I import data using
cat script | redis-cli -h localhost -p 7000 -c --pipe
it was reporting a lot of MOVED
it seems that in pipe mode, the tool is not equipped with redirect potentials

Besides, when I insert get command into the script, the pipe line not even return a result in stdout. Can any one tell me how to get through it?
I can, but I don't want to write python again.
