Trying to see if it's possible to use the Railway Public API to "Run Now" a cron job. If so, what would the graph payload look like?

Heya, that would be the deploymentInstanceExecutionCreate mutation which takes an input object with serviceInstanceId

Interesting, I'm calling deploymentInstanceExecutionCreate, and it keeps giving me this:

Run-Now mutation returned errors:

[

{

"message": "Problem processing request",

"traceId": "7613847951943220687"

}

]

I'm pretty sure my GraphQL Query is correct:

def trigger_run_now(service_instance_id):
    query = """
    mutation deploymentInstanceExecutionCreate($input: DeploymentInstanceExecutionCreateInput!) {
      deploymentInstanceExecutionCreate(input: $input) {
        id
        status
        startedAt
      }
    }
    """

    variables = {
        "input": {
            "serviceInstanceId": service_instance_id,
            }
        }

    headers = {
        "Authorization": f"Bearer {RAILWAY_API_KEY}",
        "Content-Type": "application/json",
    }

    response = requests.post(
        RAILWAY_GRAPHQL_URL,
        headers=headers,
        json={"query": query, "variables": variables},
    )

    payload = response.json()

    if "errors" in payload:
        print("Run-Now mutation returned errors:")
        print(json.dumps(payload["errors"], indent=2))
        return None

    return payload.get("data", {}).get("deploymentInstanceExecutionCreate")

Brody (another one of our engineers) has a template you might be able to use directly for exactly this purpose. Otherwise you can reference it when constructing your graphql mutations. This might help you out -> https://github.com/brody192/railway-cron/pkgs/container/railway-cron

I was looking into the docs and the Postman collection.

I'm still getting [

{

"message": "Problem processing request",

"traceId": "7613847951943220687"

}

]

So I looked into the network traffic on the Railway frontend, and it's giving me a serviceInstanceId that's no where to be found in any of the previous API calls.

Hey Sammy,

I am unsure about which Postman you are referring to, but the link that Echo provided above should suffice.
