应用程序在请求访问令牌时崩溃

我正在尝试使用授权码获取访问令牌:

curl --basic --user "{client_id}:{client_secret}" -X POST -d "grant_type=authorization_code&code={code}&state={state}" http://127.0.0.1:5000/oauth/token

我通过了 状态 我请求授权码时的参数:

http://127.0.0.1:5000/oauth/authorize?response_type=code&client_id={client_id}&state={state}

但我的身份验证服务回应:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request.  Either the server is overloaded or there is an error in the application.</p>

我在调试模式下检查了执行,Authlib正在尝试获取 状态 输入 OAuthRequest 但是找不到。
我搞不懂我做错了什么?

路线:

@bp.route("/oauth/authorize", methods=['GET'])
@login_required
def authorize():
    user = current_user()
    return server.create_authorization_response(grant_user=user)


@bp.route('/oauth/token', methods=['POST'])
def issue_token():
    return server.create_token_response()
