Amend Plan Resource Change To Allow For Optional Blocks

[bendbennett]

Module version

v0.16.0

Relevant provider source code

The issue is described in more detail in timeouts.Block causes error in modify plan set.

Briefly, defining a block within the schema, in this instance, for timeouts and then omitting timeouts from configuration generates an error.

func (e *exampleResource) GetSchema(ctx context.Context) (tfsdk.Schema, diag.Diagnostics) {
	return tfsdk.Schema{
		/*...*/        
		Blocks: map[string]tfsdk.Block{
			"timeouts": timeouts.Block(
				ctx,
				timeouts.Opts{
					Create: true,
					Update: true,
					Delete: true,
				},
			),
		},
	}, nil
}

Terraform Configuration Files

resource "example_resource" "example" {
}

Debug Output
