Pero también quieres que acepte nuevos elementos. Y cuando los elementos no existían antes, los crea y devuelve un código de estado HTTP de 201 "Created".

Para lograr eso, importa `JSONResponse`, y devuelve tu contenido allí directamente, configurando el `status_code` que deseas:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

    subprocess.run(["git", "push", "origin", branch_name], check=True)
    logging.info("Creating PR")
    pr = r.create_pull(title=message, body=message, base="master", head=branch_name)
    logging.info(f"Created PR: {pr.number}")
    logging.info("Finished")
