Using Neos & Flow
1
Suddenly (because a week ago was everthing fine and in my local machine i have no problem) I get such an error while I upload any Media. Cannot find any similar issue. What causes this problem?

Exception while property mapping for target type "Neos\Media\Domain\Model\Asset", at property path "": Missing constructor argument "resource" for object of type "Neos\Media\Domain\Model\Asset".
