PHP notice

Ever since your last update, we are receiving a large number of PHP notices as follows

WP_Scripts::localize was called incorrectly. The $l10n parameter must be an array. To pass arbitrary data to scripts, use the wp_add_inline_script() function instead. Please see Debugging in WordPress for more information. (This message was added in version 5.7.0.)

As the message indicates, you are using wp_localize_script to pass data to javascript, but instead, you should be using wp_add_inline_script

Those notices flood our logs, making it especially hard to identify actual issues.
