Steps Reproduce:
1: Install the module using Composer with the command: composer require 'drupal/c2pa_sign:^1.0@alpha'.
2: When we try the configuration of another module it shows a warning.
- For example, we are using the "LibreTranslate Translator" module,
- went to/admin/tmgmt/translators and added a new provider.
- After inserting the information when we try to add a new provider, it shows an warning, the warnings mentioned below.
Warning: Undefined array key "username" in Drupal\wordsonline_connector\WordsOnlineTranslatorUi->validateConfigurationForm() (line 162 of modules\contrib\wordsonline_connector\src\WordsOnlineTranslatorUi.php).
Warning: Undefined array key "password" in Drupal\wordsonline_connector\WordsOnlineTranslatorUi->validateConfigurationForm() (line 163 of modules\contrib\wordsonline_connector\src\WordsOnlineTranslatorUi.php).

I've attached an image illustrating my actions—installing the module and searching within the extended panel.
