Unable to read terraform variables.tf files into may go program

I am attempting to write a go program that reads in a terraform variables.tf and populates a struct for later manipulation. However, I am getting errors when attempting to "parse" the file. I Am hoping someone can tell me what I am doing wrong:

Code:

package main    import (      "fmt"      "io/ioutil"      "log"      "os"        "github.com/hashicorp/hcl/v2"      "github.com/hashicorp/hcl/v2/gohcl"      "github.com/hashicorp/hcl/v2/hclsyntax"  )    type Config struct {      Upstreams []*TfVariable `hcl:"variable,block"`  }    type TfVariable struct {      Name string `hcl:",label"`      // Default     string `hcl:"default,optional"`      Type        string `hcl:"type"`      Description string `hcl:"description,attr"`      // validation block      Sensitive bool `hcl:"sensitive,optional"`  }    func main() {      readHCLFile("examples/string.tf")  }    // Exits program by sending error message to standard error and specified error code.  func abort(errorMessage string, exitcode int) {      fmt.Fprintln(os.Stderr, errorMessage)      os.Exit(exitcode)  }    func readHCLFile(filePath string) {      content, err := ioutil.ReadFile(filePath)      if err != nil {          log.Fatal(err)      }        fmt.Printf("File contents: %s", content) // TODO: Remove me        file, diags := hclsyntax.ParseConfig(content, filePath, hcl.Pos{Line: 1, Column: 1})      if diags.HasErrors() {          log.Fatal(fmt.Errorf("ParseConfig: %w", diags))      }        c := &Config{}      diags = gohcl.DecodeBody(file.Body, nil, c)      if diags.HasErrors() {          log.Fatal(fmt.Errorf("DecodeBody: %w", diags))      }        fmt.Println(c) // TODO: Remove me  }  

ERROR

File contents: variable "image_id" {    type        = string    description = "The id of the machine image (AMI) to use for the server."    sensitive   = false  }    variable "other_id" {    type        = string    description = "The id of the machine image (AMI) to use for the server."    sensitive   = true  }  2021/03/13 19:55:49 DecodeBody: examples/string.tf:2,17-23: Variables not allowed; Variables may not be used here., and 3 other diagnostic(s)  exit status 1  

Stack driver question is sadly for hcl1
