I don't know what i do wrong, but when i tried to do checkout, there's an error and i can't finish the checkout. See the picture below for the detail.

After click Place Order : Error 1

Error on inspect element :

Error 2

Error on service :

Error 3


For these kinds of errors:

  • Check your Magento log under var/log and var/report folders.
  • If still not see any error, please check your server logs (Apache, Nginx)
  • I checked the var/report and found this {main}";s:3:"url";s:67:"/rest/default/V1/carts/mine/estimate-shipping-methods-by-address-id";s:11:"script_name";s:10:"/index.php";}, is that the error? – Edwin Widhiyanto Nov 4 '17 at 3:55
  • Did you check log under var/log folder? – Khoa TruongDinh Nov 4 '17 at 4:03
  • Here's the thing in log exception file [2017-11-06 01:46:16] main.CRITICAL: RuntimeException: Source class "" for "Magento\Framework\App\Response\Http\Interceptor" generation does not exist. in /var/www/html/xxxxxxxx.com/public_html/vendor/magento/framework/Code/Generator.php:185 – Edwin Widhiyanto Nov 6 '17 at 1:49

below are the few solutions which can help to resolve the problem.

1) Stores > Configuration > Customer > Customer Configuration > Name and Address Options: Number of Lines in a Street Address make it 2 please set it as 1

2) Please check your sales_sequence_meta and sales_sequence_profile tables sales_sequence_profile enter image description here

sales_sequence_meta enter image description here

make sure both have correct value as per your current store id. this will resolve the problem.
