upstream sent unexpected FastCGI record: 3 while reading response header from upstream client

• Regarding: Snuffleupagus
• Situation: Upon activating Snuffleupagus where SELinux is enforced, all my laravel-based php applications show the following error coming from Snuffleupagus:

FastCGI sent in stderr: "PHP message: PHP Fatal error: [snuffleupagus][0.0.0.0][config][log] Invalid configuration file in Unknown on line 0" while reading response header from upstream
upstream sent unexpected FastCGI record: 3 while reading response header from upstream client:, server:, request: "GET / HTTP/2.0", upstream: "fastcgi://unix:/opt/alt/php-fpm74/usr/var/sockets/name.sock:", host: ""

Removing snuffleupagus reverts everything working.

Please advise what is wrong or how to make snuffleupagus work.

It seems that you have an invalid configuration file. Care to share it here?

You should have more logs above this error message indicating what went wrong, but from a cursory look:

• sp.disable_xxe.enable(); is now sp.xxe_protection.enable();
• you need to set sp.global.secret_key
