Checked with latest oc , the issue has fixed:

[root@preserver-workloadrhel-1 ~]# oc version 
Client Version: 4.7.0-202012170204.p0-38273af

[root@preserver-workloadrhel-1 ~]# oc image append -h
Add layers to container images

....
Usage:
  oc image append [flags]

Examples:
  # Remove the entrypoint on the mysql:latest image
  oc image append --from mysql:latest --to myregistry.com/myimage:latest --image '{"Entrypoint":null}'
and the command works well. 

`oc image append   --from  library/mysql:latest --filter-by-os=linux/amd64  --to  localhost:5000/openshifttest/mysqltest2:latest --image '{"Entrypoint":null}' `
