How to set the EffectiveDate for WateFor event in JSON?

[smadurange]

Hi,

I have the following workflow definition:

{
    "Id": "AutomaticReply",
    "Steps": [
        {
            "Id": "OnMoReceived",
            "StepType": "While",
            "Inputs": {
                "Condition": "1"
            },
            "Do": [[
                {
                    "Id": "WaitForMo",
                    "StepType": "WaitFor",
                    "Inputs": {
                        "EventName": "\"MoReceived\"",
                        "EventKey": "\"MOIN\"",
                        "EffectiveDate": "DateTime.Now"
                    },
                    "Outputs": {
                        "Mo": "step.Data"
                    },
                    "NextStepId": "SendMt"
                },
                {
                    "Id": "SendMt",
                    "StepType": "HttpRequest",
                    "Inputs": {
                        "BaseUrl": "http://localhost:5006/api/v1/test/",
                        "Resource": "message",
                        "Method": "POST",
                        "Headers":{
                            "@Authorization": "Bearer xxx",
                            "@Content-Type": "application/json"
                        },
                        "Body": {
                            "destination": "data.Mo.Source",
                            "text": "data.Mo.Text"
                        }
                    }
                }
            ]]
        }
    ]
}

When I start this workflow (I'm using Conductor) using the http request:

curl --location --request POST 'http://localhost:5000/api/workflow/AutomaticReply' \
--header 'Content-Type: application/json' \
--data-raw '{
    
}'

I get the following exception

fail: WorkflowCore.Services.WorkflowExecutor[0]

How do I set DateTime.Now in json? I'm following the syntax given here.

[danielgerlag]

Have you tried a JSON datetime like 2012-04-23T18:25:43.511Z ?

[smadurange]

I need to set the datetime dynamically to the current time, hence the attempt to use DateTime.Now. It might even be a good idea to set the default EffectiveDate to DateTime.Now instead of DateTime.Min as it is easier to specify a hardcoded old date to process all received events actually.

[marcselis]

Maybe try System.DateTime.Now?

[danielgerlag]

This is not the same as workflow core... the scripting engine here is Python
see https://conductor-core.readthedocs.io/en/latest/primitives/
Maybe try datetime.now()
