Cannot use the library with SimpleSAML

When trying to generate a SAMLRequest object from an incoming string, the library crashes.

The following is from the Message constructor: https://github.com/simplesamlphp/saml2/blob/master/src/SAML2/Message.php#L143

    protected function __construct(string $tagName, DOMElement $xml = null)
    {
        $this->tagName = $tagName;
        $this->id = Utils::getContainer()->generateId();

The container is part of the compat layer with SimpleSAML. The generateId method uses the Random library from SimpleSAML

use SimpleSAML\Utils\HTTP;
use SimpleSAML\Utils\Random;
use SimpleSAML\Utils\System;
use SimpleSAML\Utils\XML;

    /**
     * {@inheritdoc}
     * @return string
     */
    public function generateId() : string
    {
        /** @psalm-suppress UndefinedClass */
        return Random::generateID();
    }

It's even marked as supressed in Psalm.

Start in src/SAML2/Message.php around the Message constructor and trace Utils::getContainer()->generateId() through the SimpleSAML compatibility layer. Reproduce construction of a SAMLRequest from an incoming string and inspect the SimpleSAML Random dependency and Psalm suppression. Done means the library no longer crashes during this construction path.
