Adding fields to existing slice error

Ok I see, you were right, this is related to the thread you linked at the beginning. It's something we are aware of and still have no ETA or clear plans on modifying this. I totally understand that this can become a problem if it makes the front end break.

What you can do is add extra validation to your Rich text fields so that they don't trigger an error, e.g.:

  <RichText  render={ slice.fields.ipf_field_namet || [ ] }  />
