plugin not working

hi
I’m trying to get this plugin to work with my woo-commerce site but it is not working.

I got the following error in the error log.

PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘WC_CheckoutAddressAutocomplete’ does not have a method ‘wcaf_save_image’ in /home/test/example/wp-includes/class-wp-hook.php on line 288, referer: https://www.example.com/wp-admin/options-general.php?page=wc-af-options

I tired with other plugins and those plugin works ( but not in the ways I want) so there is no problem with my API keys or anything related to google.

There is no responses when I start typing in the address lookup field and google’s dashboard shown no request.

Any idea on how I can make your plugin works for my site?

thanks
