SSH Key scan failed trying to build custom Docker under Bullseye

General
1

Hardware: Raspberry PI 4 with 8Gb Ram
OS: PI OS Bullseye Full distribution
All updates to Bullseye done
Docker standard image : 2.1.3 is running OK
Docker Custom Git freshly clone.
I was able to build several Custom Docker Node-red images under PI OS Buster.
The final lines of the log are:
ssh-keyscan failed, no more retries left
The command '/bin/sh -c ./known_hosts.sh /etc/ssh/ssh_known_hosts && rm /usr/src/node-red/known_hosts.sh' returned a non-zero code: 1
