Original GitHub issue: https://github.com/Seldaek/monolog/issues/1789

Monolog version 3.2

I'm experiencing strange behavior from Monolog when using any logging method.

ErrorException: Warning: Object of class Monolog\Level could not be converted to int
#12 /vendor/monolog/monolog/src/Monolog/Logger.php(314): Monolog\Logger::addRecord
#11 /vendor/monolog/monolog/src/Monolog/Logger.php(614): Monolog\Logger::error
#10 /src/MyFile.php(107): Service\MyFile::foobar

Inside foobar method I'm just executing
$this->logger->error('lorem ipsum');

I am still trying to understand why this is happening.
I tried to reproduce the steps in 3v4l.org and on my local env, but this only happens on my prod env.

Can this be related to this package, or is this something with opcache, maybe? Any idea how to fix this?

addRecord has an argument type being int|Level, so PHP should not try to convert the argument to int

Seems like an issue on your end but I can't imagine what would cause this. Perhaps incorrect version installed? Or like two versions in parallel from different pieces of software you run?

I mean opcache could be a thing if you don't clear it on deploy and you have some old or new Logger class in there, but it sounds weird even then..

This same thing happens to us. And affects only servers where Instana is installed (instana.io)

I bet that for us Instana hooks into monolog in PHP process and now does it using old interface.

@sakarikl Thanks for a clue! I'm not using Instana, but maybe I have another tool that is doing something like it.

I got a patch file from instana support that basically just changed enum usages to integers. And no timeline when actual fix would be available. :)

Hello,

Yeah sorry but we are not going to patch this like that, it makes no sense. They should make sure to update their support to include Monolog 3.
