How to set values within the sys property?

I want to set the creation date of an entry as I am importing from another CMS.

Everything works great except that my values for sys.createdAt are ignored.

My code:

contentfulNews = await environment.createEntryWithId(
  'blogPost',
  newsEntry.id,
  {
    sys: {
      createdAt: newsEntry.created,
    },
    fields,
  }
)

Anything I need to do to be able to alter sys.createdAt? I tried to pass a string and a JS-Date object. Both didn’t work.

Thanks a lot, Benedikt

@dlitvakb hey ho 😃 still around all the time, just as customer, not as employee 🙃

Yeah I see and this makes actually sense.

I will use a field now for publicationDate, this also allows my editors later on to change the field as it will order the blog posts.

Just one thing:

Can you state in the management docs website, that this is api generated metadata and can not be changed? As mentioned above, I think the one sentence is misleading.
