Delete All Requests Button Not Working Properly

[holysor]

I encountered an issue with the "Delete All Requests" button in the Sample Service interface. The button is intended to clear all recorded requests, but it does not function as expected. After clicking the button, the requests remain in the list, and refreshing the page still shows the same records.

Steps to Reproduce:
1、Navigate to the Sample Service interface.
2、Click on the "Delete All Requests" button (trash icon).
3、Observe that the requests are not removed from the list.
4、Refresh the page to confirm the requests persist.
