Fatal error after updating from 7.4 to 7.5 - incorrect declaration of method as Craft has a different version of React

[michielroding]

Deployer Version

v7.5.0

Target OS

macos 14.5

Which PHP version are you using?

PHP 8.3

Content of deploy.php or deploy.yaml

<?php

namespace Deployer;

require 'recipe/common.php';

host('example.com')
    ->setLabels(['stage' => 'production']);

Steps to reproduce

Given the example deploy script with Craft v4.17.2, the following output is given:

dep deploy:setup stage=production 
task deploy:setup
PHP Fatal error:  Declaration of React\Promise\Internal\FulfilledPromise::then(?callable $onFulfilled = null, ?callable $onRejected = null): React\Promise\PromiseInterface must be compatible with React\Promise\PromiseInterface::then(?callable $onFulfilled = null, ?callable $onRejected = null, ?callable $onProgress = null) in /…/vendor/react/promise/src/Internal/FulfilledPromise.php on line 37

Fatal error: Declaration of React\Promise\Internal\FulfilledPromise::then(?callable $onFulfilled = null, ?callable $onRejected = null): React\Promise\PromiseInterface must be compatible with React\Promise\PromiseInterface::then(?callable $onFulfilled = null, ?callable $onRejected = null, ?callable $onProgress = null) in /…/vendor/react/promise/src/Internal/FulfilledPromise.php on line 37

This seems to be due to vendor/react/promise/src/PromiseInterface.php (from Craft v4.12.7, latest version) being a different version from vendor/deployer/deployer/deps/vendor/react/promise/src/PromiseInterface.php.
