Drupal 10: Fatal error, logger must be compatible with Psr\Log\AbstractLogger

Problem/Motivation

If you install the module (both 5.0.x and 5.1.x) in Drupal 10, you get a WSOD and this error message:

Fatal error: Declaration of Drupal\backup_migrate\Drupal\Environment\DrupalSetMessageLogger::log($level, $message, array $context = []) must be compatible with Psr\Log\AbstractLogger::log($level, Stringable|string $message, array $context = []): void in /app/web/modules/contrib/backup_migrate/src/Drupal/Environment/DrupalSetMessageLogger.php on line 22

For more, see the Change record Update code that implements \Psr\Log\LoggerInterface due to Psr/Log version 3 .

Steps to reproduce

1. Download the dev version in Drupal 10: composer require drupal/backup_migrate:5.0.x-dev@dev
2. Install the module: drush in backup_migrate
3. Go to /admin/config/development/backup_migrate
4. Se the Fatal error: Declaration of Drupal\backup_migrate\Drupal\Environment\DrupalSetMessageLogger [...] message

Proposed resolution

Make the logger Drupal 9 and Drupal 10 compatible:

As long as the return typehint is implemented then it is possible to be compatible with Drupal 9 & 10. Changing ::log to have the void return type will make a logger compatible with both major versions.

public function log($level, $message, array $context = []): void {
