I am getting an issue on Magento 2.2 when trying to create promotion rule. This error occurs sometimes and the error disappears if run Magento upgrade command. But it comes again sometime.

The Issue:

My team recently ran into this on v2.3.1 of Magento Community, and it appears that you may have an attribute with an attribute_model of type Magento\Eav\Model\Entity\Attribute when the system is actually expecting type Magento\Catalog\Model\ResourceModel\Eav\Attribute

For reference, you can check out the line of code where that error is being thrown. For me it's here: https://github.com/magento/magento2/blob/2.3.1/app/code/Magento/SalesRule/Model/Rule/Condition/Product.php#L70-L71

You'll see a comment on the type of what that variable is (expected to be):

/* @var $attribute \Magento\Catalog\Model\ResourceModel\Eav\Attribute */

The Solution:

Well, my solution was to update that attribute_model value in the eav_attribute and/or eav_entity_type tables directly - you'll see some others have done this in the Magento issue linked to in Rafael's answer. After this, you'll want to make sure you run a reindex and clear cache. Hope that helps!

Just a note: if you continue to run into this issue, it may be the case that you have some code (maybe custom or a 3rd party module) that is adding/updating an attribute and setting that attribute_model value incorrectly

Magento – Command line user does not have read and write permissions on generated directory

More likely than an issue with bin/magento (even though actually there is no executable bit on any level of access) there is an issue with a generated folder. As you can read in documentation for v2.2 compiled files changed their paths to /generated/*

I assume that you have properly set privileges bits for the previous version but maybe you missed setgid/uid bits and therefore user executing PHP script does not have access to this file (all is a file in Unix, also dirs).

As per Magento 2.2 Release Note

Security enhancements

In general, we’ve removed serialize/unserialize from most the code to improve protection against remote code execution attacks. We’ve enhanced protection of code where use of object serialization or unserialization was unavoidable. Additionally, we’ve increased our use of output escaping to protect against cross-site scripting (XSS) attacks.

So you need to inject \Magento\Framework\Serialize\Serializer\Json class for serialize and unserialize values.

use following code for serialize and unserialize values.

protected $serialize;

public function __construct(
    \Magento\Framework\Serialize\Serializer\Json $serialize
) {
    $this->serialize = $serialize;
}

public function serialize($value){
    return $this->serialize->serialize($value);
}

public function unserialize($value){
    return $this->serialize->unserialize($value);
}
