This status code indicates that the server has encountered an unexpected condition or error that prevented it from fulfilling the request made by you. It's a generic error message that doesn't provide specific details about what went wrong, as the server may not want to disclose sensitive information to the client for security reasons. here is what u can do to resolve this: 1. Check the HTTP method (POST, etc.) and request parameters configured in both Postman and Appian. Ensure they are consistent. 2.Confirm the content type and any other headers in your request which is required by the API.
