rebuildhttpdconf error "Not a HASH reference at /usr/local/cpanel/Cpanel/EA4/Conf/Tiny.pm line 82."

Symptoms

Unable to rebuild httpd.conf using /scripts/rebuildhttpdconf

Description 

The following error may occur when trying to rebuild httpd.conf.

[22:14:52 server root ~]cPs# /scripts/rebuildhttpdconf
Not a HASH reference at /usr/local/cpanel/Cpanel/EA4/Conf/Tiny.pm line 82.
[22:14:55 server root ~]cPs#

The following file may be missing

/etc/cpanel/ea4/ea4-metainfo.json

and needs ea-cpanel-tools to be reinstalled.

Workaround

There may be a CloudLinux RPM in place if CloudLinux was uninstalled. This will require that RPM to be forcibly removed by itself with

rpm -e ea-cpanel-tools --nodeps

and then installed again with

yum install ea-cpanel-tools
