Change index_name from a field

I do not understand what you refer to with “index_name” — in the GraphQL documentation, there does not seem to be such a field, neighter on card, nor on field. What exactly are you refering to?

Yes, there is a indexName in card, see:

{
  card(id: xxxxxxxx) {
    fields {
      array_value
      date_value
      datetime_value
      filled_at
      float_value
      indexName
      name
      report_value
      updated_at
      value
    }
  }
}
