I was trying to use the Gutenberg Editor in a new D11.1 instance PHP 8.4 and I see the usual "he explicit nullable type" that is appearing on many modules:
Deprecated: _gutenberg_is_gutenberg_enabled(): Implicitly marking parameter $entity as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/gutenberg/gutenberg.module on line 1405
Deprecated: Drupal\gutenberg\MappingFieldsHelper::getMappedFields(): Implicitly marking parameter $template as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/gutenberg/src/MappingFieldsHelper.php on line 264
Deprecated: Drupal\gutenberg\MappingFieldsHelper::getMappedFieldsFromContent(): Implicitly marking parameter $content as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/gutenberg/src/MappingFieldsHelper.php on line 303
Deprecated: Drupal\gutenberg\Parser\BlockParser::parse(): Implicitly marking parameter $filter_callable as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/gutenberg/src/Parser/BlockParser.php on line 89
Install the latest 4.x-dev release of the module, and you'll see the errors, I'm not sure if other versions are affected.
All the explicit nullable type in the function parameter

I create a MR that fixes these warnings, I believe the pipieline errors were already there: https://git.drupalcode.org/project/gutenberg/-/merge_requests/223
Feel free to review.
