Fetch task details including its state information

[najoshi7]

Hello prefect community,

I want to fetch task's state details. I tried following query in a python program:

client = prefect.Client()

query = {
    "query": {
        "flow": {
            "id": True,
            "name": True,
            "flow_run": {
                "state": True,
                "id": True
            }
        }
    }
}

x = client.graphql(query)

But, it results into following error:
requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: http://localhost:4200/graphql

Somebody please help.

Thanks.

Hi..
Any suggestions?

Hi @najoshi7

Your issue is that you must pluralize flow_run when nested there e.g.

In [14]: client = prefect.Client()
    ...: 
    ...: query = {
    ...:     "query": {
    ...:         "flow": {
    ...:             "id": True,
    ...:             "name": True,
    ...:             "flow_runs": {
    ...:                 "state": True,
    ...:                 "id": True
    ...:             }
    ...:         }
    ...:     }
    ...: }
    ...: 
    ...: x = client.graphql(query)

In [15]: x
Out[15]: 
{
    "data": {
        "flow": [
            {
                "id": "7761cd4a-292c-4571-8b0d-0f158861ca4a",
                "name": "empty",
                "flow_runs": []
            },
            {
                "id": "22abcaa0-d22b-4217-b4cd-48102aa7622a",
                "name": "empty",
                "flow_runs": []
            },
            {
...

I'll work on exposing a better error message!
