[Bitbucket Cloud] Git push using OAuth 2.0 token is not working: "remote: Invalid credentials"

Bitbucket Development Bitbucket Cloud

I’m trying to push some changes from a script locally.
I already created a consumer for OAuth 2.0 following the Use OAuth on Bitbucket Cloud guide. Already obtain the token from https://bitbucket.org/site/oauth2/access_token successfully.
But when I try to push my changes (after adding and commit my changes):

git_url = f"https://oauth2:{oauth_token}@bitbucket.org/{my_repository}.git"
result = subprocess.run(["git", "push", "-u", git_url, source_branch], capture_output=True, text=True)

I got this error (token and repo anonymized for security purposes):

(Pdb) result
CompletedProcess(args=['git', 'push', '-u', 'https://oauth2:XXXXXXXXX@bitbucket.org/YYYYYYYYY/ZZZZZZ.git', 'upgrade-version'], returncode=128, stdout='', stderr="remote: Invalid credentials\nfatal: Authentication failed for 'https://bitbucket.org/YYYYYYYYY.git/'\n")

To ensure I’m not using the wrong repository I directly copied and pasted from navigator by clicking in clone report and contains Workspace+repository name

To obtain the OAuth Token:

def obtain_oauth_token(client_id, client_secret):
    # Bitbucket OAuth token endpoint
    token_url = "https://bitbucket.org/site/oauth2/access_token"

    # OAuth token request parameters
    data = {
        "grant_type": "client_credentials"
    }

    # OAuth client credentials for authentication
    auth = (client_id, client_secret)

    try:
        # Send POST request to obtain OAuth token
        response = requests.post(token_url, data=data, auth=auth)

        # Check if request was successful
        if response.status_code == 200:
            # Parse JSON response and extract access token
            token_data = response.json()
            access_token = token_data.get("access_token")
            return access_token
        else:
            error_data = response.json()
            print(f"Failed to obtain OAuth token: <{response.status_code}> {error_data['error_description']}")
            return None
    except Exception as e:
        print("Error:", e)
        return None

Also, I tried to:

command = ["git", "remote", "add", "oauth", f"https://oauth2:{oauth_token}@{repository_url}"]
result = subprocess.run(command, capture_output=True, text=True)

and later push using oauth:

result = subprocess.run(["git", "push", "oauth", source_branch], capture_output=True, text=True)

But I’m having same issue than before:

(Pdb) result
CompletedProcess(args=['git', 'push', 'oauth', 'upgrade-version'], returncode=128, stdout='', stderr="remote: Invalid credentials\nfatal: Authentication failed for 'https://bitbucket.org/YYYYYYYYY/ZZZZZZ.git/'\n")

Also I tried with https://x-token-auth:{oauth_token}@bitbucket.org/{workspace-id}/{repo}.git:

git_url = f"https://x-token-auth:{oauth_token}@bitbucket.org/{repository}.git"
result = subprocess.run(["git", "push", "oauth", source_branch], capture_output=True, text=True)

But it didn’t work either

My internal variable repository contains the workspace and repo.

Can someone help me on this?
