RawData trait uses 'mixed' type hints incompatible with PHP 7.4

[daniolivet8]

Description

The RawData trait in both v1 and v2 uses mixed type hints (property declaration, parameter, and return type), which were introduced in PHP 8.0. This causes a fatal error on PHP 7.4 despite composer.json declaring "php": "^7.4 || ^8.0".

Affected files

• lib/versions/v1/Traits/RawData.php
• lib/versions/v2/Traits/RawData.php

Error

Argument 1 passed to Pipedrive\versions\v2\Model\DealItem::setRawData() must be an instance of Pipedrive\versions\v2\Traits\mixed, instance of stdClass given, called in vendor/pipedrive/pipedrive/lib/versions/v2/ObjectSerializer.php on line 405

PHP 7.4 interprets mixed as a class name within the current namespace instead of the native type.

Current code (v2 example)

trait RawData
{
    private mixed $rawData;

    public function getRawData(): mixed
    {
        return $this->rawData;
    }

    public function setRawData(mixed $rawData): void
    {
        $this->rawData = is_object($rawData) && property_exists($rawData, 'data') ? $rawData->data : $rawData;
    }
}

Suggested fix

Remove mixed type hints to maintain PHP 7.4 compatibility (the @var, @param, and @return PHPDoc annotations already document the types):

trait RawData
{
    /** @var mixed */
    private $rawData;

    /** @return mixed */
    public function getRawData()
    {
        return $this->rawData;
    }

    /** @param mixed $rawData */
    public function setRawData($rawData): void
    {
        $this->rawData = is_object($rawData) && property_exists($rawData, 'data') ? $rawData->data : $rawData;
    }
}

Environment

• SDK version: 15.4.0
• PHP version: 7.4.33
