AWS Api网关授权者+ Cognito用户池不起作用{“消息”：“未经授权”}

我正在尝试将aws api网关授权者与cognito用户池一起使用。当我使用AWS API网关控制台进行测试时，它工作正常。

I am trying to use aws api gateway authorizer with cognito user pool. It is working fine when i test using aws api gateway console.

但是当我尝试在api中启用授权时，它会显示 message： Unauthorized。请检查下面的屏幕截图

But when i try enabling the authorization in the api it says "message": "Unauthorized". Please check below screenshot

API网关控制台屏幕截图-可以正常使用

API Gateway Console Screenshot - This works fine

邮递员屏幕截图-不起作用

Postman Screen shot - Not working

有人可以帮忙吗？
