LocalizationUtility::translate(): Argument #1 ($key) must be of type string, null given

[linawolf]

TYPO3 v12.4.6: I get the following error on opening a record in the backend module, even though the table exists and has a a title:

(1/1) TypeError
TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate(): Argument #1 ($key) must be of type string, null given, called in /var/www/html/vendor/cobweb/external_import/Classes/ViewHelpers/Be/TableTitleViewHelper.php on line 56

When calling https://example.ddev.site/typo3/module/externalimport/data/DataModule/viewConfiguration?table=tx_news_domain_model_news&index=mykey

Configuration:

$GLOBALS['TCA']['tx_news_domain_model_news'] = [
