Research direction

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.

Written by the indexing model from the issue text.

Description

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.
