I'm trying to use the GraphQL API to to retrieve the event logs for a given run and seem to be running into a little syntax error - not very familiar with GraphQL. here's the error:

{
  "error": {
    "data": null,
    "errors": [
      {
        "message": "Variable \"runId\" of type \"ID\" used in position expecting type \"ID!\".",
        "locations": [
          {
            "line": 1,
            "column": 18
          },
          {
            "line": 2,
            "column": 21
          }
        ]
      }
    ]
  }
}

and my query:

query LogsForRun($runId: ID){
  logsForRun (runId: $runId) {
    __typename
    ... on EventConnection {
      events {
        __typename 
        ... on ExecutionStepStartEvent {
          runId
          timestamp
          stepKey
        }
      }
    }
  }
}

with this variable:

{
  "runId": "1d71f590-e925-42eb-af6c-831d524e1945"
}

I believe you just need to refine the type here: notice the

ID!

(signifying that

$runId

will be non null)

query LogsForRun($runId: ID!){
  logsForRun (runId: $runId) {
    __typename
    ... on EventConnection {
      events {
        __typename 
        ... on ExecutionStepStartEvent {
          runId
          timestamp
          stepKey
        }
      }
    }
  }
}

ah yes, thanks a bunch!
