Fatal error with Drupal 11.4.0

I install local a new drupal with 11.4.0 and install Tome modules and at first the site work or at least I can navigate like a normal new drupal site, but when I try to create a new node I get the same error:

Fatal error: Declaration of Drupal\tome_sync\Normalizer\EntityReferenceItemNormalizer::normalize($field_item, $format = null, array $context = []): ArrayObject|array|string|int|float|bool|null must be compatible with Drupal\serialization\Normalizer\EntityReferenceFieldItemNormalizer::normalize($field_item, $format = null, array $context = []): array in /var/www/html/web/modules/contrib/tome/modules/tome_sync/src/Normalizer/EntityReferenceItemNormalizer.php on line 17

I was able to fix the site doing some change in code.

I change the files in /tome_sync/src/Normalizer/

so I switch from:

public function normalize($field_item, $format = null, array $context = []): ArrayObject|array|string|int|float|bool|null

to something like:

public function normalize($field_item, $format = null, array $context = []): array

and basically change all files there to use []): array

It's a rather naive change, but at least the site started working and I was actually able to start exporting with Tome and updating the website online.

If I check with drush ws I still get the errors:

PHP Deprecated: Drupal\tome_sync\Normalizer\PathAliasNormalizer::__construct(): Implicitly marking parameter $entity_type_repository as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/tome/modules/tome_sync/src/Normalizer/PathAliasNormalizer.php on line 42

But At least I get site online again. I hope Tome modules get a better solution Soon.

Hi. I prefer that you continue with the solution in the other issue. My solution involved asking the AI, and I don't have much knowledge about how the Tome module works. I think it would complicate things if I added my code.
