   Hello,
   
   It's not working, here's the code:
   
   ```
   res_template=$(cat <<EOF
   {%
   %}    
   {*ngx.arg[1]*}
   {*ngx.arg[2]*}
   EOF
   )
   
   
   echo "Creating Response Transformer Plugin"
   plugin_config_payload='{
       "desc": "Response Transformation Plugin",
   	"plugins": {
           "body-transformer": {
               "response": {
                   "input_format": "json",
   		"template": "'"$res_template"'"
               }
           }
   	}
   }'
   ```
   
   The first ngx argument is showing empty space and the second is showing the true boolean flag. 
   It seems as though I am trying to access the body at a point where it is no longer there but at the same time, I am using the body transformer plug-in, so I should be able to get it.
