Steps to Reproduce

1. terraform apply

Output error

│ Error: error getting search index information: json: cannot unmarshal array into Go struct field IndexMapping.mappings.fields of type mongodbatlas.IndexField
│ 
│   with mongodbatlas_search_index.skus,
│   on mongodb.tf line 82, in resource "mongodbatlas_search_index" "skus":
│   82: resource "mongodbatlas_search_index" "skus" {

Please note that the index has been manually updated via Atlas UI to get that index array definition.

@stefanosala thank you - we'll have the team take a look and report back.

@stefanosala this is being caused by a bug in the Atlas go client we use. The bug has been fixed so we'll need to update the provider to be able to use it. We will be working on that quickly.
