This error occurs if any other module creates the block plugin instance and calls the build method:
```
TypeError: Drupal\social_media_links\SocialMediaLinksPlatformManager::getPlatformsWithValue(): Argument #1 ($platforms) must be of type array, null given, called in /var/www/html/web/modules/contrib/social_media_links/src/Plugin/Block/SocialMediaLinksBlock.php on line 358 in Drupal\social_media_links\SocialMediaLinksPlatformManager->getPlatformsWithValue() (line 85 of /var/www/html/web/modules/contrib/social_media_links/src/SocialMediaLinksPlatformManager.php).
```
And that's fine, doing this in custom code could be easily fixed by passing extra configurations. But when other modules do that, you'll see the error. For example, the experience builder → module.
\Drupal\experience_builder\Plugin\ExperienceBuilder\ComponentSource\renderComponent()
1. Install experience builder module, create first page to be able to populate it with components
2. Install social_media_links module
3. Check the website logs and see the error
In the build method of the SocialMediaLinksBlock assume that platforms might be empty:
```
$platforms = $this->platformManager->getPlatformsWithValue($config['platforms'] ?? []);
```
instead of
```
$platforms = $this->platformManager->getPlatformsWithValue($config['platforms']);
```

Prepared the MR with a fix; I think it can now be reviewed, as the errors/warnings in the pipeline are not related to the changes made.
