Date.now() for esriFieldTypeDate?

[NaciDilekli]

Based on Robert Scheitlin, GISP‌'s answer, I have been trying to set a date attribute programmatically using the following expression:

evt.adds[0].attributes.eventdate = new Date(Date.now());    ‍‍

This generates the following error: "Error: Unable to complete operation"

However, if I try to set the value of a text field it works fine, e.g.:

evt.adds[0].attributes.description = "test";‍‍

So I suppose the problem has to do with the field type. How can this be resolved?

Here is my entire code for reference. Thanks

Naci,

  What is the field type for your eventdate field?

[NaciDilekli]

Robert,

It is esriFieldTypeDate. Here is the full information of the field: "eventdate ( type: esriFieldTypeDate , alias: Date , editable: true , nullable: true , length: 8 )"

This is the service I am using: Layer: Wildfire Response Points (ID: 0)

Naci,

Try:

evt.adds[0].attributes.eventdate = new Date(Date.now()).getTime();
