Bug description

I use AWS S3 for primary file storage. A file called "test.jpg" uploads fine, also "test1.jpg" is no problem, but uploading "test 1.jpg" fails with no warnings/errors what so ever!

When I check the network tab in Chrome (via F12) I see a "PUT" with remote.php/webdav/test/test%201.jpg and a "PROPFIND" with the same URL there is says (with HTML formatting) "App not installed:" (but not telling which app..)

The same happens with a file WITHOUT a space, but there the PROPFIND returns an XML result! (and all goes wel..)

Steps to reproduce

1. create a fresh install of Nextcloud 25.0.3
2. use PHP 8.1
3. upload a file with a space in it!

Expected behavior

1. it should upload the file
2. it should tell me what went wrong (even loglevel set to 3 doesn't tell me anything..

none..

Additional info

When I configure Apache to use PHP 7.4 with the same Nextcloud installation there isn't ANY problem!

So this must be related to PHP 8 somehow.. but I installed all the modules, there are no warnings what so ever in 'settings/admin/overview'

PS: @szaimen I updated the bug description a bit, hope it helps

AD: I use AWS S3 for primary file storage, but since PHP7.4 works fine, one would not think it to be a part of the problem?

(I knew I mentioned something "with spaces" here before!)

I have a test-setup that I had previously updated to Nextcloud 25 and PHP8.1 I now had a serious bug in my nextCloud and decided it was time to update my "production Nextcloud" to PHP 8.1 and I forgot I had the "space problem" mentioned here..

The bug of it already going wrong at uploading made finding the cause hard.. but after the upgrade I had a file already there with a space in it and viewing also didn't work.. now I found the cause!

#37852 fixes this bug!! Not only does it make it possible to view a file with a space in it, now I can also upload a file with a space in it! (I tested this with my test-setup, which does not have this "Q&D-fix" an there I still can not upload, but my production-version it does work! me happy ;)
