Re: 500 error While testing Custom Connector

Hi @NikTan,


What’s your current situation? Does it work for you now?


Generally, error code 404 means that a setting in an action of the flow doesn’t function as expected. While error 500 means that the failure is temporary. Please check the doc about troubleshooting for more details:


Please also make sure you have followed the steps that displayed in this doc on Create a custom connector from a Postman collection:
