GelfHandler "Message is invalid: additional key contains invalid characters"

Monolog version 1|2|3?

{
    "name": "monolog/monolog",
    "version": "3.8.0",
    "source": {
        "type": "git",
        "url": "https://github.com/Seldaek/monolog.git",
        "reference": "32e515fdc02cdafbe4593e30a9350d486b125b67"
    }
}

With the basic log call

$logger->info('Hello World', ['invalid context' => 'test']);

[2024-11-21T12:21:39.764122+00:00] Cron.ERROR: Uncaught Exception RuntimeException: "Message is invalid: additional key 'ctxt_invalid context' contains invalid characters" at /Users/ybelenko/Sites/bdo_pay/vendor/graylog2/gelf-php/src/Gelf/Publisher.php line 58 {"exception":"[object] (RuntimeException(code: 0): Message is invalid: additional key 'ctxt_invalid context' contains invalid characters at /Users/ybelenko/Sites/bdo_pay/vendor/graylog2/gelf-php/src/Gelf/Publisher.php:58)"} []

I guess Monolog should prepare $context and $extra for Publisher and strip spaces.
Valdiation part in vendor/graylog2/gelf-php/src/Gelf/MessageValidator.php:

foreach ($message->getAllAdditionals() as $key => $value) {
    if (!preg_match('#^[\w\.\-]*$#', $key)) {
        $reason = sprintf(
            "additional key '%s' contains invalid characters",
            $key
        );

        return false;
    }
}
