Please help me to fix this grapqhl module related warning.

This error (related to graphql module) is coming in our drupal website after upgrade php 8.1:

Deprecated function: Return type of Drupal\graphql\Plugin\TypePluginManagerAggregator::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in include() (line 5 of /code/web/modules/contrib/graphql/src/Plugin/TypePluginManagerAggregator.php).

when I hite the url domain/update.php/selection.

Can anyone help me to fix it?

It looks that you are using Drupal GraphQL in version 3.x and you should migrate to 4.x to have compatibility with newer PHP version. The problem is in this file , which had last commit almost 5 years ago...

There is existing issue and pull request about this, but it seems to be inactive a bit.

If you cannot upgrade library, try use a tip from pull request - enforce base graphql library version in composer.json and apply patches - author of that comment says that it worked.
