PHP 8.1 error with WHMCS 8.7.3

[netwood]

Upgraded PHP to 8.1.

I searched the community but did not find an answer.

When I try to edit anything on a clients profile page - in the admin section - I get the following PHP errors:

TypeError: array_map(): Argument #2 ($array) must be of type array, null given in /home/XXXXX/includes/hooks/prevent_aes_encrypt.php:21
Stack trace:
#0 /home/XXXX/includes/hooks/prevent_aes_encrypt.php(21): array_map('strtolower', NULL)
#1 [internal function]: prevent_AES_ENCRYPT(Array)
#2 /home/XXXXX/vendor/whmcs/whmcs-foundation/lib/Hook/Manager.php(0): call_user_func('prevent_AES_ENC...', Array)
#3 /home/XXXXX/vendor/whmcs/whmcs-foundation/lib/Hook/Manager.php(0): WHMCS\Hook\Manager->run('ClientDetailsVa...', Array)
#4 /home/XXXXX/vendor/illuminate/support/Facades/Facade.php(261): WHMCS\Hook\Manager->validate(Object(WHMCS\Validate), 'ClientDetailsVa...', Array)
#5 /home/XXXXX/includes/functions.php(0): Illuminate\Support\Facades\Facade::__callStatic('validate', Array)
#6 /home/XXXXX/admin/clientsprofile.php(0): run_validate_hook(Object(WHMCS\Validate), 'ClientDetailsVa...', Array)
#7 {main}

It works fine with PHP 7.4

Please advice.

Your developer need to fix this prevent_aes_encrypt.php to work with PHP 8.1

Thanks for your reply.

WHMCS is the developer I guess.
Have not done any modifications to any scripts.

Any suggestions what I can do to fix it?

That is not a script created by WHMCS so you must have made a modification.

Most have been some old plugin that was enabled at some point.
I disabled it and now PHP 8.1 works fine.

Thanks for the help.

Likely. That AES issue was the major flaw from back in 2013, if memory serves. By changing user details to a specific string WHMCS could be tricked into revealing admin details. Nasty business, that.
