I’m trying to update our CakePHP 4.4 to 4.5.

I am running `bin/cake upgrade rector --rules cakephp45 src/`

But then I get: `PHP Fatal error: Uncaught Error: Undefined constant "RESOURCES" in /[...]/cakephp/config/app.php:69`

Line 69 is:

`'locales' => [RESOURCES . 'locales' . DS],`

Which matches this: [app/config/app.php at 4.x · cakephp/app · GitHub](https://github.com/cakephp/app/blob/4.x/config/app.php)

Any help is appreciated.

Thank you! For some reason I was missing that line.

after each minor (and especially major) update its always a good idea to compare the current recommended cakephp/app template with what your app is currently at.

If there is something in the app template which is not in your app it should be copied over
