Google's Code for running the tests on the api_server doesn't seem to work

[TinotendaMakuza]

curl -X POST http://0.0.0.0:8000/apps/my_sample_agent/users/u_123/sessions/s_123
-H "Content-Type: application/json"
-d '{"state": {"key1": "value1", "key2": 42}}'

When I paste the above code as is, it returns a few errors, the first ones being

curl: (7) Failed to connect to 0.0.0.0 port 8000 after 0 ms: Could not connect to server
curl: (3) URL rejected: Bad hostname

The rest are about how -H and -d are not cmdlets etc

Below is some of what I have done in an attempt to get the code to work:

1. Wrapping the 42 in double quotes thinking it is a syntax error
2. Replacing the address with localhost:8000, as my research indicated that apparently 0.0.0.0:8000 is not a valid address, and I need to use localhost:8000 or 127.0.0.1:8000 instead.
3. Putting the code all on one line.
4. Running in a ps1, bash and even json file using both VS Code's terminal and my local terminal (Powershell and CMD for both).

I am supposed to get a success message with a log of the session, but instead I keep getting the above error message in my terminals, and {"detail":"Not Found"} on the localhost:8000 and 127.0.0.1:8000, and "It looks like the webpage at http://0.0.0.0:8000/ might be having issues, or it may have moved permanently to a new web address." on 0.0.0.0:8000.

What was your command line to start your api_server?
