Code snippet that reproduces the problem

File from error:

<?php

/**
 * This file was automatically generated by generate:mutationEndpoints
 */

declare(strict_types=1);

namespace Slant\Normalizer\Endpoints\Generated;

use Firehed\API\Interfaces\HandlesOwnErrorsInterface;
use Slant\Normalizer\Attributes\ContextInterface;
use Slant\Normalizer\Endpoints\AuthenticatedEndpointInterface;
use Slant\Normalizer\Endpoints\Traits\GeneratedMutationEndpoint;

class GeneratedMutationRemoveAliasFromConnectedNode implements
    AuthenticatedEndpointInterface,
    HandlesOwnErrorsInterface
{
    use GeneratedMutationEndpoint {
        __construct as traitConstructor;
    }

    public function __construct(ContextInterface $context)
    {
        $this->traitConstructor($context, new \Slant\Normalizer\Mutations\RemoveAliasFromConnectedNode());
    }

    // Not done by provided mutation because this is used in a static
    // context (and the definition hasn't been updated)
    public function getUri(): string
    {
        return '/mutations/remove_alias_from_connected_node$';
    }
}

I can provide the trait in question if it's relevant, but my guess is the problem is around the aliased trait method import.

Expected output

No error/no crash. This analyzes and runs fine in 8.0.
