Error after saving new record or switching type

[Artifex1]

Bug Report

Current Behavior I installed the extension, included the TS and wanted to create a new record, but as soon as I want to save it or switch the type I get the following error:

Oops, an error occurred!
Argument 1 passed to TYPO3\CMS\Core\DataHandling\Model\RecordStateFactory::TYPO3\CMS\Core\DataHandling\Model\{closure}() must be of the type string, null given

Expected behavior/output Well I expect to have a new record.

Environment

• TYPO3 version: 9.5.1
• news version: 7.0.7
• Is your TYPO3 installation set up with Composer (Composer Mode): yes
• OS: Windows 10
• PHP Version 7.2.11

Help is highly appreciated :-)
