I think you don't have a prefect server running or you did not set the right API URL. If it's the former, run

pefect server start

in a separate terminal before running your flow. If it's the latter, specify the

PREFECT_API_URL

variable before running your flow.

I do have the server set. API and is running at http://127.0.0.1:4200 and i still get the same error

Then try setting the PREFECT_API_URL before running your workflow. But it should work by default.

Okie Gang!! I solved it. with the help of chatGPT. anyways I did this, just following the terminals responses.

(venv) PS C:\Users\User\Desktop\Projects\Clients\tongs-web-scraper> prefect config set PREFECT_API_URL="<http://127.0.0.1:4200/api>"
Set 'PREFECT_API_URL' to '<http://127.0.0.1:4200/api>'.
PREFECT_API_URL is also set by an environment variable which will override your  
config value. Run `unset PREFECT_API_URL` to clear it.
Updated profile 'local'.
