@Bianca Hoch Hi, I am working on a workflow poc using prefect. For poc, I am choosing prefect as a self-hosted server. Here is the steps which I had followed: 1. installed prefect (prefect server start) 2. i could open the ui at localhost:4200/ 3. now i run the same code which is given in the quick start guide "my_gh_workflow.py"

attached the error which I am facing.

I tried replacing the api with with my cloud login as well like:

prefect cloud login -k <my-token>

export PREFECT_API_URL="https://api.prefect.io/accounts/{account-id}/workspaces/{workspace-id}/api"

but I couldn't succeed. Is there anything which I'm missing?

Hey welcome to the prefect community 🙂 I think for local server you should replace

https

with

http

instead. For cloud, the URL is slightly different from what you have, it should be

<https://api.prefect.cloud/api/accounts/{account-id}/workspaces/{workspace-id}>

instead of

<https://api.prefect.io/accounts/{account-id}/workspaces/{workspace-id}/api>

. I hope this helps 🙂

Hi Laxmi and Danne! Laxmi, you're correct that the

PREFECT_API_URL

would start with

https://api.prefect.cloud/api/

to use Prefect Cloud. Danne, if you're self-hosting your own server, you'll want to set your

PREFECT_API_URL

to

<http://127.0.0.1:4200/api>

. The command to set this is:

prefect config set PREFECT_API_URL=<http://127.0.0.1:4200/api>

@Laxmi and @Bianca Hoch I was using http://127.0.0.1/api but I was facing

@danne have you also tried downgrading urllib3 to <2.x.x ? urllib3 v2 works with python3.10 so if that's an option, that should also work

yes seems to be an issue with mac. here are some mac specific solutions, may be give that a try?

Omg, let me try or I'll try in some linux system.
