I have an issue on checkout page and we are getting below error on console. It looks like address object is not loaded correctly on quote object and we are getting different error each time.
i know here someone asked this question but nothing find proper solution
billing-address.min.js:1 Uncaught TypeError: Cannot read property 'getCacheKey' of null at UiClass.<anonymous> (billing-address.min.js:1) at Function.notifySubscribers (knockout.min.js:133) at Function.valueHasMutated (knockout.min.js:149) at Object.observable [as billingAddress] (knockout.min.js:143) at select-billing-address.min.js:2 at checkout-data-resolver.min.js:14 at Function._.some._.any (underscore.min.js:15) at Function.some (observable_array.min.js:4) at Object.applyBillingAddress (checkout-data-resolver.min.js:14) at Object.resolveBillingAddress (checkout-data-resolver.min.js:13)
Any help would be appreciated.
