An error occurred when creating an Excel file.

Is your feature request related to a problem? Please describe.
An error occurred when creating an Excel file after enabling the files_antivirus application.

When creating a new TXT file, the wrapStream method is called and the file is created correctly; however, when creating an Excel file, the file_put_contents method is called and the file is not created correctly.

This may be due to the added file_put_contents method lacking a Try-Catch statement.

Nextcloud version:31.0.2.
onlyoffice app version:9.7.0.
files_antivirus app version:6.0.0.

Describe the solution you'd like
Can correctly create new Excel, Word, and PowerPoint files.

Describe alternatives you've considered
No response.

Additional context
No response.

@a54758398 It looks like you didn't configure files_antivirus correctly. It tries to invoke ClamAV but can't find the binary: The antivirus executable could not be found at /usr/bin/clamscan.

Please go to Admin settings -> Security and make sure that you configured the integration with ClamAV correctly.

[a54758398]

Thank you for your reply. We understand the configuration you described; However, code analysis shows that the method lacks a try catch statement for exception handling, so optimization is proposed.

[st3iny]

We discussed this and won't accept a fix for now.

Viruses should not be silently accepted/ignored when the scanner backend is not configured properly. Instead, an exception should be thrown to make admins aware of the misconfiguration.
