While accessing a Magento admin system configuration page, facing the below error that prevents the save config button.
Uncaught TypeError: locations.each is not a function
When clicking on system.js, seems to be loading from the PayPal_Braintree module.
locations.each(function (loc) {
$('[data-ui-id="select-groups-braintree-section-groups-braintree-groups-braintree-paypal-groups-styling-groups-button-'+loc+'-fields-paypal-location-'+loc+'-button-type-value"]').change(function () {
hidePaypalSections();
});
});
