rebuildhttpdconf error "Not a HASH reference..."

Symptoms

Unable to rebuild httpd.conf using /scripts/rebuildhttpdconf

Description 

One of the following errors 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.

[16:18:39 server root~]cPs# /scripts/rebuildhttpdconf
Not a HASH reference at /usr/local/cpanel/Cpanel/IP/AutoDomain/TemporaryDomain/Check.pm line 62.

The following file may be missing or empty:

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

and needs the ea-cpanel-tools package to be reinstalled.

Workaround

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

rpm -e ea-cpanel-tools --nodeps

and then installed again with:

yum install ea-cpanel-tools
