Send an EMail action - BadGateway Error

[jaina]

Hi,

Can someone explain the reason why BadGateway persist in a send an email action? What are the possible reason?

In my case, here's the error encountered but when I re-run the workflow it became okay. 

{

  "error": {

    "code": 504,

    "source": "asia-001.azure-apim.net",

    "clientRequestId": "e32c326d-fadb-4b57-8617-276b6ca7408c",

    "message": "BadGateway",

    "innerError": {

      "status": 504,

      "message": "Request failed. Try again later.\r\nclientRequestId: e32c326d-fadb-4b57-8617-276b6ca7408c",

      "error": {

        "message": "Request failed. Try again later."

      },

      "source": "office365-sea.azconn-sea.p.azurewebsites.net"

    }

  }

}
