Dropbox integration issue/ Error Log

Hi all,

I have two issues with my fresh Nextcloud installation:

  1. Migrating files from Dropbox to Nextcloud is not working
  2. The Error Log gets flooded with entries

I installed NC via an image file on a root server. Since the NC, SQL, PHP, etc. were outdated I updated the SQL & Co via SSH (Putty) and for Nextcloud I used the web-updater.

Re issue 1:
Afterwards I installed the Dropbox integration and connected it (default Nextcloud Dropbox OAuth app). Unfortunately no files are being transferred. Its only showing me “Dropbox import process will begin soon”.
I also tried using a self created Dropbox OAuth app - same issue.

For cron.php I am using an external webcron service.

The errorlog is showing the following (excerpt):

{"reqId":"fJvscKBoLG5udRpO6J3N","level":1,"time":"2021-07-28T13:11:52+00:00","remoteAddr":"149.224.176.230","user":"admin","app":"no app in context","method":"GET","url":"/index.php/apps/files/","message":"Deprecated event type for OCA\\Files::loadAdditionalScripts: Symfony\\Component\\EventDispatcher\\GenericEvent is used","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36","version":"21.0.3.1"}

Re issue 2:
In addition to the log entries from the Dropbox App I get many other entries in the log file. Please find an example below:
