Difference between Windows and Linux ZIP files

[DdotKdot]

Hey there,

I recognized a really strange bug. I'm developing a custom extension for Espo for importing invoices. I packed it on Linux with:

zip -r extension.zip .

and uploaded the created ZIP file to the server. I got a 500 error "Bad Server Response".
If I pack the same files with windows, with the native packer or 7zip, everything works fine. 7zip for Linux isn't working too.
Is this my fault (can I pack the zip another way)? Or can you fix something?

Thank you,
Dennis

No one any idea? No fix avaiable, no tipps, nothing?
It's really annoying and Espo depends so much on ZIP files...

Hi Dennis

We will appreciate if you investigate the issue and help us to fix. Actually I pack extensions in Linux.
