RuntimeException: Failed to start the session because headers have already been sent by "/code/web/core/modules/big_pipe/src/Render/BigPipe.php" at line 244.

The issue trigger when cron process "Renew recurring order" and "Close recurring order" jobtype from the queue. As per Trent Crawford , the payment is being closed on payment on RecurringOrderManager::close(). This causes the PaymentOrderUpdater to run in the kernel destructor (after headers have already been sent). so they have merged a request in #3323736 → to the commerce. The changes in the merged request already exists in the commerce 3 dev. Still commerce_recurring throws the error and queue job got failed. Anyone else faces this?

Here is the complete reply of Trent Crawford .

The issue is very strange, sometime it works, other time it fails. these two orders with 251 id is process successfully. see the screenshot.
