OpenVAS connector doesn't work and How to connect for using API

[Mettthew]

First question

Hi all, I downloaded ArcherySec today following the instructions given in the documentation:
git clone https://github.com/archerysec/archerysec.git
cd archerysec
NAME=<NAME OF USER> EMAIL=<EMAIL ID OF USER> PASSWORD=<USER ACCOUNT PASSWORD> bash setup.sh

I subsequently use the command:
bash run.sh

and going to the specific address and port, I get the classic screen where I login, so everything seems to be working correctly for the time being.

Reading the documentation it is specified that you have to set up the connectors and the ones I used are Zaproxy and OpenVas.
For Zaproxy I have no problem but when I go to create the one for OpenVas, once I enter the required information I get the following screen when I try to save:

(Before doing these operations, I have both servers active that allow the use of Zaproxy and OpenVas)

I use Kali Linux virtual machine and If there is anything I am doing wrong, please let me know I am not very knowledgeable about these things.

Second question
I tried using the API supported by ArcherySec, but I can't make the connection and I don't understand exactly what I should do:

Reading the documentation it is specified to download:
pip install PyArchery
but once installed and trying later from a python script:
from archery import api
I get the error indicating that there is no archery module.

Having this problem, I later tried using the API by directly using endpoints via a script in Python, I then tried translating the following CURL:

Using the following Script:

the response I get by running this script is error, It appears that the page is not found by returning a 404 error, If you know how I could solve these problems I would really appreciate it.

and a doubt I have if I'm using the right endpoint, that is 0.0.0.0:8000 is the host and port where Archery runs when I use the bash command run.sh, Is it right to use this?
