502 Bad Gateway error in Power Automate Trigger

Hi,

I want to use Adobe Sign for one of my projects. 

I am trying to use Adobe Sign Trigger in Power Automate but I am getting a 502 Bad Gateway error.

- I am using it when the agreement is completed successfully trigger.

But the error is coming for all the triggers.

In my other flow, I used Adobe Sign Action which is working but the trigger is not working. 

Error:

{
  "error": {
    "code": 502,
    "source": "uk-001.azure-am.net",
    "clientRequestId": "6ecf-9b01-4e26-a4c-989c7194c",
    "message": "BadGateway",
    "innerError": {
      "code": "CANNOT_PROCESS_REQUEST",
      "message": "An error occurred and the request could not be processed"
    }
  }
}
