I had problem with connecting my app to database. I try do it with this https://docs.sencha.com/extjs/6.5.1/...mysql_php.html guide. I have errors, so I'm trying do exactly the same steps on generated DirectApp without changing anything. I still get the same errors.

I checked on forum there's thread about this issue https://www.sencha.com/forum/showthread.php?311102 but it's left without answer.
