get requests work, but post requests from telegrams do not What could be the reason for this error?

[rustatian]

@veleton777 Seems, that smt with your payload. Looks like the issue from PHP, @wolfy-j could you please take a look?

[wolfy-j]

Most likely something echoed to the STDOUT, check your Loggers or switch to Unix sockets.

now an error of a different type

[rustatian]

@veleton777 I can guess, that there is no data in the socket $prefixBody === null || $prefixLength !== 17, but, we definetely should make error messages more user friendly.

[rustatian]

@veleton777 Could you please check the data availability in the socket?

[veleton777]

Как мне можно проверить наличие данных в сокете?

[veleton777]

Через сервер workerman сокеты работают

[rustatian]

Как мне можно проверить наличие данных в сокете?

Не мог бы ты писать на английском, пожалуйста, так как данная проблема может возникнуть у тех, кто не говорит по русски.

1. How could I check the data in the UNIX socket. I am not very familiar with PHP, but I found this function in PHP stdlib (I guess) link.
2. Socket works as expected with workerman. Could you please provide the following:
   • Operating system type (Linux (Ubuntu, Arch, etc) or Windows).
   • PHP, spiral, and RR versions.
   • Steps to reproduce this issue (with a minimal sample of code). With commands which you executed. Thanks.

this error appears when running roadrunner

./rr serve

[veleton777]

on ubuntu the same error

[rustatian]

Ok, thanks a lot. @Hunternnm, could you please take a look?

[veleton777]

I solved the error, the Viber library code contained the file_get_contents ('php://input'); I replaced it with fetching via laravel requests
