You are running wp-cli and see this error message:
1 | Unable to query OPcache status: array_key_exists(): Argument #2 ($array) must be of type array, bool given. |
This error is thrown when opcache_get_status( true ) is called and returns false because opcache is disabled and then array_key_exist looks for a 'scripts' in a bool instead of an array.

Cause: opcache is installed but not enabled for the cli
1 2 3 | php -i | grep -i opcache | grep enableopcache.enable => On => Onopcache.enable_cli => Off => Off |
Work-a-round: find the opcache cli ini file and turn opcache on for the cli
1 2 | php -i | grep -i opcache | grep ini/etc/php/8.2/cli/conf.d/10-opcache.ini, |
Edit the cli opcache ini and set opcache.enable_cli to on
1 2 3 | sudo vim /etc/php/8.2/cli/conf.d/10-opcache.ini # add on or true or 1 to turn it onopcache.enable_cli=on |
On Ubuntu 22.04 the in file will look as follows:
