In some join requests, users get stuck with the following error. What's going on? Could you help me?

Header may not contain more than a single header, new line detected at /var/www/xxxxx/vendor/symfony/http-foundation/Response.php:359)

It is technically possible to have duplicate headers in HTTP but up to the implementer to fix it.
