PHP Error: ZipArchive::getStream(): Invalid or uninitialized Zip object at /var/www/nextcloud/lib/private/Archive/ZIP.php#154

Hi everybody,

Looking at the Administration Logging utility I’m encountering the following error triggered by PHP:

Error: ZipArchive::getStream(): Invalid or uninitialized Zip object at /var/www/nextcloud/lib/private/Archive/ZIP.php#154

Unfortunately I cannot say how to reproduce it but it happens rather often.
Please, can anybody tell me to what it’s due and if I should worry about it?

Thanks in advance for any help!

I’m getting the same problem with 23.0.2. I’m including the full information below. Could you help me debug it? Apparently something’s wrong with file with id=12061, but I don’t know how to investigate further.

Actually I have the same error for many fileIds and for many users.

I think it is a bug. Read this issue.
