python-cloudflare: cli4: /zones/:demo.ps/dns_records/import - demo.ps: not found

Hello, I’ve been trying to make this work with no luck:

cli4- -post file=@demo.txt /zones/:demo.ps/dns_records/import

The result is always: cli4: /zones/:demo.ps/dns_records/import - demo.ps: not found

However most other methods are working fine, like export, add new dns record. Can anyone help ?
