UnlockField not working in CakePHP for array

I have a form that has to handle some elements as part of an array.

echo $this->Form->control('config.sys_file_id', ['type' => 'number']);
echo $this->Form->control('click_enlarge', ['type' => 'checkbox']);
echo $this->Form->control('config.max_width', ['type' => 'number']);
echo $this->Form->control('config.max_height', ['type' => 'number']);
echo $this->Form->control('config.fixed_width', ['type' => 'number']);
echo $this->Form->control('config.fixed_height', ['type' => 'number']);

This would work fine, except I need to handle config.sys_file_id with some JS.

I know that I have to call $this->Form->unlockField(), but I can’t figure out the right syntax to use when the field is part of an array.
So far I’ve tried

$this->Form->unlockField('sys_file_id');
$this->Form->unlockField('config');
$this->Form->unlockField('config.sys_file_id');
$this->Form->unlockField('config[sys_file_id]');

but the request still gets black-holed by the SecurityComponent.

I have stumbled upon these two questions How to 'unlock' a field in a CakePHP form when it is part of a hasMany association and UnlockField not working in CakePHP but they are both very old and refer to CakePHP 2, while I’m using CakePHP 4.

    The correct syntax for unlocking the input (when is an array) from the view is with a dot:

    $this->Form->unlockField('config.sys_file_id');

    https://api.cakephp.org/4.4/class-Cake.View.Helper.FormHelper.html#unlockField()

    But make sure to use $this->Form->unlockField() between the $this->Form->create() and $this->Form->end();:

    echo $this->Form->create();

echo $this->Form->control('config.sys_file_id', ['type' => 'number']);
echo $this->Form->control('click_enlarge', ['type' => 'checkbox']);
echo $this->Form->control('config.max_width', ['type' => 'number']);
echo $this->Form->control('config.max_height', ['type' => 'number']);
echo $this->Form->control('config.fixed_width', ['type' => 'number']);
echo $this->Form->control('config.fixed_height', ['type' => 'number']);

// before form end
$this->Form->unlockField('config.sys_file_id');


echo $this->Form->end();

    If you place $this->Form->unlockField('config.sys_file_id'); outside the form end() or create() you’ll get a CakePHP exception:

    FormProtector instance has not been created. Ensure you have loaded
    the FormProtectionComponent in your controller and called
    FormHelper::create() before calling FormHelper::unlockField().

    I tested this code on CakePHP 4.4 Strawbery and it works.

    If your JAVASCRIPT code is altering other fields by mistake, your problem is there.

    I had the same issue ,because I placed the Form->unlockField(‘myField’); ?> before the $this->Form->end() line, and it was no working, but I fixed moving the unlockField method after the $this->Form->create() line. Now it works!
