Cisco ASA net_put "Invalid response from server" "Signature Verified\r\n"

SUMMARY

Using net_put to scp a file onto an ASA (firepower1010) fails with the error message: msg: 'Exception received: (''Invalid response from server'', b''Signature Verified\r\n'')'

The image appears to have been sucessully copied to the device and the response 'Signature Verified' as the end of the SCP process is not seen as valid which then breaks the playbook.

COLLECTION VERSION

I am stuck using Ansible 2.9 due to distributed management of the server and 'list' is not an option. I did a force install to ensure everything was up-to-date
