Two things that I saw after updating to php 8.2:

$this->di->getShared('url')->getBaseUri();

results in:

Deprecated: Creation of dynamic property MyApp::$di is deprecated in /var/web/nginx/html/myApp/app/App.php on line 46

And

echo Phalcon\Tag::renderTitle();

results in: Deprecated: Use of "self" in callables is deprecated in /var/web/nginx/html/myApp/app/modules/public/views/phtml/partials/header.phtml on line 16

This error also occurs in:

Tag::hiddenField Model method findFirstBy{Field Name}

[zz]

so we have to lock project phalcon version to PHP8.1

For now, looks like it's an upstream issue. https://github.com/zephir-lang/zephir/issues/2405
