Changing the System's Default PHP Fails With "Error: API failure: Can't call method "get_default_string" on an undefined value at

Changing system php version from 7.3 to 7.4:
Error: API failure: Can't call method "get_default_string" on an undefined value at /usr/local/cpanel/Cpanel/WebServer/Supported/apache.pm line 367.
I have done the steps as in:

Hey there! If you're still seeing issues after making sure the plugins line is present in /etc/yum.conf and you have reinstalled that version of PHP, can you open a ticket with our team so we can check this directly? Please post the ticket number here so I can keep the community updated with our findings.

TY for the answer. Sorry there was typo in yum.conf. It seems to work now but reinstalling php gives bunch of perl errors, even when trying it again:

Interesting - I'm sorry to hear you ran into additional problems.

I'd try forcing a full update with "/scripts/upcp --force" first to make sure all the cPanel files are present on the system and working well. If that doesn't get things working, please submit a ticket with our team so we can take a look directly on the system and help get that resolved.

It turns out the custom paths that were defined in that root bashrc file were related to the issue, and after removing those Perl entries things are working well :D
