        "polling_start_time": "2023-06-07 14:11:11.841000",
        "leg_info": [
            {

            }
        ],

1. Put your request under the While Controller and use the following __jexl3() function as the condition:

   ${__jexl3("${status}" != "success",)}
   

   

2. Add JSON Extractor as a child of the request and configure it as follows:

   

3. That's it, the While Controller will run the request until polling_status attribute value is not success, once it becomes success it will exit the loop and proceed to the next Samplers or Controllers. Something like:
