How do I use nested structs for resources

Hi @KnockOutEZ :wave:

Sorry you ran into trouble here.

The issue is that the type you have specified for the Aws field in the ClusterDetails struct cannot handle null values.

The most straightforward fix is to alter the ClusterDetails struct as follows:

type ClusterDetails struct {
	ID             types.String `tfsdk:"id"`
	Name           types.String `tfsdk:"name"`
	Aws            types.Object `tfsdk:"aws"`
}

Further discussion of an analogous issue can be found in the following post - How count.index works - #2 by austin.valle

Assuming you are using something along the following lines within, for example, a Create method:

	var data ClusterDetails

	diags := req.Plan.Get(ctx, &data)
	resp.Diagnostics.Append(diags...)

	/* ... */

You should then be able to convert the value contained within data.Aws into an AWS struct by using data.Aws.ObjectAs(). Refer to Plugin Development - Framework: Object Type | Terraform | HashiCorp Developer for further information on data handling for objects.
