Error: Call to a member function getUID() on null, when uploading folder on external local share

[simm4ik]

This error is related to activity app. If I'll delete activity app everything will be ok.

Steps to reproduce

Create local folder on server ("/test" for example) owned by www-data user with write permissions.
Add created folder as external storage. Create file share link with upload permission on external storage.
Try to upload a folder using shared link.

Expected behaviour

Folder should be uploaded

Actual behaviour

Browser shows folder creation error and upload error while folder is been created.
In logs appears Error: Call to a member function getUID() on null

this does not work for me

[nickvergessen]

With the steps given in the first post, it works fine for me and I can not reproduce an issue anymore on latest master/stable20.
So check with the upcoming 20.0.1 build and post more detailed reproduction steps if it still happens for you.
