Error "Update mkParentDir failed" when using rclone with ocis

[nikslor]

Describe the bug

I run into an issue when trying to sync my home dir to ocis (2.0.0) using rclone (1.61.1). On the client side I see messages like the following:

$ rclone -v -L sync /tmp/blackhole/ocis/ storage:/test
2023/01/31 18:04:15 ERROR : foo/bar/baz/test.txt: Failed to copy: Update mkParentDir failed: Resource not found: Sabre\DAV\Exception\NotFound: 404 Not Found
2023/01/31 18:04:15 INFO  : test.txt: Copied (new)
2023/01/31 18:04:15 ERROR : webdav root 'test': not deleting files as there were IO errors
2023/01/31 18:04:15 ERROR : webdav root 'test': not deleting directories as there were IO errors
2023/01/31 18:04:15 ERROR : Attempt 1/3 failed with 1 errors and: Update mkParentDir failed: Resource not found: Sabre\DAV\Exception\NotFound: 404 Not Found
2023/01/31 18:04:15 ERROR : foo/bar/baz/test.txt: Failed to copy: Update mkParentDir failed: Resource not found: Sabre\DAV\Exception\NotFound: 404 Not Found

Steps to reproduce

• Let's assume your working dir is /tmp/blackhole/ocis
• create test.txt: echo "Hello ocis" > test.txt
• create a simple folder structure mkdir -p foo/bar/baz
• copy text.txt to that folder cp test.txt foo/bar/baz/
• start sync rclone -v -L sync /tmp/blackhole/ocis/ storage:/test

Expected behavior

I should be able to sync this folder with rclone w/o seeing such an error.

Actual behavior

I get an error with the latest OCIS stable version.

Setup

Please describe how you started the server and provide a list of relevant environment variables or configuration files.

did setcap 'cap_net_bind_service=+ep' ocis and run ocis like this:

OCIS_BASE_DATA_PATH=/var/lib/ocis
ACCOUNTS_DEMO_USERS_AND_GROUPS=false
PROXY_HTTP_ADDR=0.0.0.0:443
OCIS_URL=https://storage.0x17.ch
PROXY_TRANSPORT_TLS_KEY=/etc/letsencrypt/live/storage.0x17.ch/privkey.pem
PROXY_TRANSPORT_TLS_CERT=/etc/letsencrypt/live/storage.0x17.ch/fullchain.pem
OCIS_INSECURE=false
PROXY_ENABLE_BASIC_AUTH=true

Additional context

I had a similar issue earlier on, see: #2767

@wkloucek I think this may be related to #2767, maybe something you want to have a look at?
(I hope it's fine to highlight you - otherwise just let me know)

I also see this with rclone on a Windows 11 box syncing to the same server.

[micbar]

There was a fix in #6136 which is available on ocis master which might fix this issue.

Hi @micbar I can confirm, that this is fixed in a recent release! I tested with 3.0.0 rc3 and the problem is gone.
Awesome! Thanks a lot for the work on this!
