I'm having a really weird trouble with my extension, as the shipping method section in checkout cannot be loaded, here's what it shows in inspect element:

enter image description here

so the above POST request cannot be loaded and now I don't know where to dig into to fix this. Any idea what the cause is for this problem? thank you


Enable error reporting in php (for example uncomment #ini_set('display_errors', 1); in app/bootstrap.php) and see response of this post. Then enable debugging with xdebug and add breakpoint in place of error and continue debug.

This error is caused by many situations, so you either provide us with what the php apache error_log or the reporting from php as @KAndy mentioned.


In my case turning to "No" "Use Web Server Rewrites" made it work by adding "index.php/" before "/rest/default/V1..."
