yum update not working using Oracle Database 23ai Free Container Image Lite

I try to install git on the docker image container-registry.oracle.com/database/free:latest-lite

docker run -d --name oracledb container-registry.oracle.com/database/free:latest
docker exec -it oracledb bash

Some reason I am not able to reach https://yum-us-phoenix-1.oracle.com

 yum update

I need some hours to finde this:

[root@b24a9535f826 ~]# cat /etc/yum/vars/ociregion
-us-phoenix-1

If I remove /etc/yum/vars/ociregion entry then 'yum update' working fine.

[root@b24a9535f826 ~]# echo -n "" >  /etc/yum/vars/ociregion
[root@b24a9535f826 ~]# yum update

It is necessary to have the entry '-us-phoenix-1' in /etc/yum/vars/ociregion?
If not please remove.

I can confirm the issue and the workaround above, also when using the Oracle Database 23ai Free VirtualBox Appliance.
