I am trying to set doneDate currentDate onChange done field.

getting this error

admin > date doesn't have a "condition" property. Conditions are used to conditionally show or hide fields depending on... some condition. You can't use them to set a field's value.

It sounds like what you want would be a beforeChange hook (relevant docs page: https://payloadcms.com/docs/hooks/collections).

When the done field is modified, you can return a new value for the doneDate field inside the beforeChange hook

Worked. Thanks
