CRC validation failed

The message validation failed on the message sent to STDOUT, RR docs: https://docs.roadrunner.dev/docs, invalid message: ... means that you or some application sent an invalid raw message to STDOUT. The STDOUT stream is reserved for RR communication with the PHP process via the goridge protocol (v3).

How to fix that?

1. Check your application. All dependencies should send their messages to STDERR instead of STDOUT. You may see the output after the invalid message. It might be truncated on Windows.

2. Check any dd or echo statements you inserted. PHP workers can redirect echo automatically from STDOUT to STDERR, but only after the worker is fully initialized.

3. A worker from RR v1 was used. To update, see: link

4. OPcache is enabled with JIT, but some extensions don't support it, which leads to warnings. Adjust the error_reporting configuration (use only errors): issue

5. If you use a Symfony runtime, add APP_RUNTIME to the server environment variables, as described here: https://github.com/php-runtime/roadrunner-symfony-nyholm.
