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.

  • I think thats a js error, I don't really know where to put my breakpoint

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..."
