Hello, I haven’t used graphQL very much but I’m running a few requests similar to:

```auto
mutation {
  phones(serialNumber: { is: "R58RB492TBJ" }) {
    update(
      groupId: 177
      deploymentDate: "2022-07-07"
      deploymentStatus: { name: { is: "Reserve" } }
      profile: "Bud"
      updated: "2022-07-07T20:40:33.000Z"
    ) {
      message
    }
  }
}

```

But in some cases I want to just clear deploymentDate: instead of updating it, sending a blank value didn’t work since it’s a Date column.

Do I need to run a delete request for just that cell or something?

Thanks in advance

Hello, @NWE

Please use `null` as value to reset dates.

```auto
mutation {
  stories(id:{isNull:false}){
    update(myDate:null){message}
  }
}

```

Ah that makes sense, don’t know why I didn’t try that.  
Thanks a lot!
