you need install monolog v2.7.0 to able see problem

[engcom-November]

Thanks for the update @mrtuvn
However, monolog is not part of https://github.com/magento/magento2 git repository. Community cannot able to provide fix for it in this repository.
As per Magento devdocs, Magento uses Monolog by default. Monolog implemented as a preference for Psr\Log\LoggerInterface in the Magento application di.xml Kindly refer this guide to use the same for logging. Otherwise all questions, issue reports and fix for them should be addressed to the corresponding extension owners(support)
Thank you.

The facts

• Magento require version ^2.6 of monolog, which means that 2.7.0 is the highest version that is installed when you composer create project of magento

  magento2/composer.json

  Line 69 in 28c1f28

  "monolog/monolog": "^2.6",

• This means magento either needs to say <=2.7.0 for their monolog requirement, or fix their application code to be compatible.

Either way there is an action for magento here, when you build a version of latest magento from scratch you will pull in a monolog version incompatible with some magento code.

The maintainer of monolog thinks the implementations by magento in the data migration tool and the integration test infrastructure is, and i quote, "madness".

See Seldaek/monolog#1684 (comment) and also see #35596 (comment) where this issue affects the ability to run tests, the thing that ensures we are able to deliver robust software.
