Same issue here. Object Storage via S3.

[JUVOJustin]

Same Error with a nearly identical setup

[kesselb]

MOVE /remote.php/dav/uploads/u221219/web-file-upload-360dc11ec3f6b727dccf1f21382d298b-1579507080603/.file is related to assembly a file uploaded in chunks. I don't know how to reproduce that kind of failure. Uploading files in chunks with s3 (minio) works with my development setup.

server/lib/private/Files/Cache/Cache.php

Line 614 in d918458

$sourceData = $sourceCache->get($sourcePath);

$sourceData could be false. Probably a check is missing here. But the actual error is happening earlier.

It seems that $data is null.

$data = $source->get(); returns null.

For the record, i'm able to reproduce it every time with this test case:

• Create 5 files with the same name (if need, in different folders)
• Try to upload them all

1 file uploaded, 4 errors

And in the logfile 4 lines like:

Error: TypeError: Argument 1 passed to OC\Files\Cache\CacheQueryBuilder::whereFileId() must be of the type int, null given, called in /srv/lib/private/Files/Cache/Cache.php on line 655

[williamsmt]

I can consistently repro this issue, but with a different test case. Same specs as @acsfer

1. Open NC to establish session
2. Place NC in maintenance mode
3. Refresh session from step 1 and confirm MM screen
4. Take NC out of MM
5. Refresh session and navigate to any app ('Deck' is used here, but 'Files' and 'Photos' app also repro'd)
