Nextcloud installer fails with; 'FileExistsError'

[wouterbr]

The nexcloud app seems to install just fine, but adding a nextcloud website afterwards, the installer fails

I got ithe following message when trying to create a personal Nextcloud;
'FileExistsError' object is not subscriptable
I deleted and installed nextcloud in the appstore
