So i had the 5.3.10 version and i added the code to my functions.php
function my_acf_init() {
acf_update_setting('google_api_key', 'your_api_key');
}
add_action('acf/init', 'my_acf_init');
My API key is domain-less, i worked with the temporary fix (changing the key in acf-input.min.js) in the past month and it went fine.
Now i get MissingKeyMapError in wp-admin and i cant use the maps
Updated to 5.4 BETA and its still the same
The “data-key” is just “field_5778e0a4fa700”
