I am sure someone more in the Symfony know will be able to elaborate but shouldn't it look more like this: https://docs.sentry.io/platforms/php/guides/symfony/configuration/symfony-options/#callables?

That's not the issue. The class I used is implemented to have __invoke method which makes the service itself a callable. In fact I'm using the very same approach for before_send and there it works:

sentry:
    options:
        before_send: App\Library\Logger\Processor\BeforeSendProcessor

services:
    App\Library\Logger\Processor\BeforeSendProcessor: ~

The issue with integrations is that in the current version it always wants an array and passing a callback isn't allowed despite what the error message says.

This seems to be the case...

Bump

This doesn't look like a bug, but rather a missing feature: looking at the code of version 3.5.x I don't see anything pointing out to supporting passing a callable rather than an array of integrations

Ah yeah I got confused... it was implemented in sentry-php but sentry-symfony was never adapted to support it.

Note: I wanted to disable ModulesIntegration since the package versions are useless traffic for us but once again I ran into this exact issue. :(
