Im getting nowhere on this. So frustrating

Is caption even part of the array from wp_get_attachment_metadata?

Because I cant get it to return it, and a var dump doesnt seem to show it:

 array(5) {
  ["width"]=>
  int(400)
  ["height"]=>
  int(300)
  ["file"]=>
  string(19) "2018/07/400x300.png"
  ["sizes"]=>
  array(3) {
    ["thumbnail"]=>
    array(4) {
      ["file"]=>
      string(19) "400x300-150x150.png"
      ["width"]=>
      int(150)
      ["height"]=>
      int(150)
      ["mime-type"]=>
      string(9) "image/png"
    }
    ["medium"]=>
    array(4) {
      ["file"]=>
      string(19) "400x300-300x225.png"
      ["width"]=>
      int(300)
      ["height"]=>
      int(225)
      ["mime-type"]=>
      string(9) "image/png"
    }
    ["square"]=>
    array(4) {
      ["file"]=>
      string(19) "400x300-300x300.png"
      ["width"]=>
      int(300)
      ["height"]=>
      int(300)
      ["mime-type"]=>
      string(9) "image/png"
    }
  }
  ["image_meta"]=>
  array(12) {
    ["aperture"]=>
    string(1) "0"
    ["credit"]=>
    string(0) ""
    ["camera"]=>
    string(0) ""
    ["caption"]=>
    string(0) ""
    ["created_timestamp"]=>
    string(1) "0"
    ["copyright"]=>
    string(0) ""
    ["focal_length"]=>
    string(1) "0"
    ["iso"]=>
    string(1) "0"
    ["shutter_speed"]=>
    string(1) "0"
    ["title"]=>
    string(0) ""
    ["orientation"]=>
    string(1) "0"
    ["keywords"]=>
    array(0) {
    }
  }
}

Here is the code I tried:

<?php
$id = get_field('primary_image');
$img_meta = wp_get_attachment_metadata( $id );
echo $img_meta[image_meta][caption];
?>
