Unable to get "Alert id" from the request "List alerts for an incident"

Hi, while testing the request call ā€œList alerts for an incidentā€ I am not getting the required response as mentioned in the document. It is giving the response 200Ok status but not giving the ā€œalert idā€. due to which ā€œGet an Alertā€ call request is unable to run. kindly guide me why i am not getting the alert id in the response?
the screenshot of call is attached.

Hard to tell without knowing if the incident you’ve selected actually has alerts associated with it.

Should be a simple cURL call like this:
curl --request GET
–url ā€˜https://api.pagerduty.com/incidents/INC_ID_HERE/alerts’
–header ā€˜accept: application/vnd.pagerduty+json;version=2’
–header ā€˜authorization: Token token=YOUR_TOKEN_HERE’
–header ā€˜content-type: application/json’
