I'm trying to create and merge a gitlab mr using python script, the mr was created without any error, but I got an error message while trying to merge it "422, {"message":"Branch cannot be merged"}", how can i get more details about the error? Is there any issue with my script? Thanks

The functions used to create and merge it:

def create_merge_request(token, project_id, source_branch, target_branch, title, description):
    """Créer une Merge Request sur GitLab."""
    url = f"{GITLAB_HOST_HTTPS}/api/v4/projects/{project_id}/merge_requests"
    headers = {"PRIVATE-TOKEN": token}
    data = {
        "source_branch": source_branch,
        "target_branch": target_branch,
        "title": title,
        "description": description,
        "merge_when_pipeline_succeeds": False,  # Désactiver la fusion conditionnelle

        "squash": True                        # Ne pas écraser les commits
    }

    response = requests.post(url, headers=headers, json=data)

    if response.status_code == 201:
        mr_data = response.json()
        print(f"Merge Request créée avec succès : {mr_data.get('web_url')}")
        return mr_data  # Retourne les détails de la MR
    else:
        print(f"Erreur lors de la création de la Merge Request : {response.json()}")
        return None

    print(f"URL utilisée pour le merge : {url}")
    response = requests.put(url, headers=headers) #, json=data

    if response.status_code == 200:
        print("Merge Request mergée avec succès.")
        return response.json()
