Uncaught exception PimpleAdapter.php

[Aybee]

Hallo David, ich habe die 3.0.0-alpha2 in eine frische Contao 3.5.37 (xampp) installiert (Composer). Dann einen Zeitstrahl angelegt und dem Zeitstrahl ein Item hinzugefügt. Wenn ich mir dieses Item im BE jetzt anzeigen lassen möchte (Bleistift) bekomme ich folgende Fehlermeldung.
