Reading JSON data in a variable with type of `types.Dynamic`

Terraform Providers Plugin Development
1

I am writing a Custom Terraform Provider for Ansible Forms using the Terraform plugin framework (GitHub - hashicorp/terraform-plugin-framework: A next-generation framework for building Terraform providers. v1.8.0). How can I read JSON string in a field with type types.Dynamic? The JSON string itself contains a map where values types are different.

Here is my DS model:

type JobDataSourceModel struct {
	CxProfileName types.String  `tfsdk:"cx_profile_name"`
	...
	Extravars     types.Dynamic `tfsdk:"extravars"`
	...
}

Here is Schema() method:

func (d *JobDataSource) Schema(ctx context.Context, req datasource.SchemaRequest, resp *datasource.SchemaResponse) {
	resp.Schema = schema.Schema{
		Attributes: map[string]schema.Attribute{
			...
			"extravars": schema.DynamicAttribute{
				MarkdownDescription: "",
				Computed:            true,
			},
			...
		},
	}
}

Read() method:

func (d *JobDataSource) Read(ctx context.Context, req datasource.ReadRequest, resp *datasource.ReadResponse) {
	var data JobDataSourceModel
	...
	data.Extravars = types.DynamicValue(restInfo.Data.Extravars)
	...
}

Has anyone used this new type? :slight_smile: I can reflect on the example.
