I just tested export functionality and it seems it works. Do you have any additional information how it is possible to reproduce the issue?

Looking at the latest release docs, file_format and input_format was moved thus causing a break:

Downgrading import-export to 3.3.9 is a potential short-term fix.

Fixed in #398
