Installing monolog module in Drupal 9 and trying to use any drush command caused the following error:
PHP Fatal error: Declaration of Drupal\monolog\Logger\Logger::addRecord(int $level, string $message, array $context = []): bool must be compatible with Monolog\Logger::addRecord(int $level, string $message, array $context = [], ?Monolog\DateTimeImmutable $datetime = null): bool in /app/web/modules/contrib/monolog/src/Logger/Logger.php on line 41
Install monolog 2.2.0 on Drupal 9 and afterwards try using any Drush command.
Add ?Monolog\DateTimeImmutable $datetime = null to the addRecord method in Drupal\monolog\Logger\Logger
Needs review
2.2
Code
it's working for me. I have checked the issue with monolog 2.2.0 on Drupal 9.5. after setup all the configuration's for log file, I am not getting any error related to logging & it's successfully writes the logs in private folder.
Please refer the module help for configurations.
