LogicException when quering for Bank

[ghost]

I did the following:

$bav = Bav::DE();
$bank = $bav->getBank('38651390');

This triggers the following Exception:

Fatal error: Uncaught exception 'LogicException' with message 'Start and end should be defined for bankId=37050299 (exception=The contextCache object should exist!)' in vendor/jschaedl/bav/library/Bav/Backend/Parser/BankDataParser.php:95

Another bank code triggering this behavior is for example 38650000. I had a quick look at the BankDataParser and the data file, but I am not sure what triggers the behavior above.
