Azure Devops Pipeline Run makes Git Error?

ACTION: I have a git project on my work azure devops that I pull normally using ssh authentication. I tryed to run a pipeline on my work azure devops and work self-hosted windows computer from azure GUI to test CI features. It's a hello word project, just testing if everything is set-up correctly.

EXPECTED:

Seeing "Hello word" results from Azure Pipelines jobs terminal.

RESULT:

Pipeline use an automated script and run some git commands witch try to init and fetch a https project with wrong credentials and fails. Here's the log with some redacted info.

INFO:

1. I tried going to C:\agentW_work\1\s and using git remote set-url origin ssh... as specified here : https://learn.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops and make a pull manually. it succeeded.

2. I tried changing C:\agentW.credentials authorizationUrl and oauthEndpointUrl values to values given to me by our DevOps.

3. I tried running another pipeline projects(from other personal azure repo, but same self-hosted computer) with a HTTP settings in configuration #2, it works. See below.

4. I have acess to my C:\Users*****(REDACTED).ssh, if i need to paste my public ssh key somewhere.

Question:

1. How do I change setting on the automated script to pull my ssh repo instead?
2. How do I change my Https Git setting so that pulling the https project works too?
