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 the 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,
            },
            ...
        },
    }
}

The 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)
    ...
}

Data returned by the Ansible Forms API is given below. The extravars field is a JSON string in the API response. I am converting a value of extravars into a map. Map values has diff types such as list, str, and boolean. That’s why I want to use types.Dynamic.

I’ve tried doing that with the code abov, but it does not work.
