Regarding wait logic in custom provider, getting "Error: couldn't find resource (21 retries)"

Hi team,

I have my custom provider, where I have implemented a wait logic to confirm the deletion of the resource

_, err := isWaitForDelete(apiService, id, d.Timeout(schema.TimeoutDelete))

Then the isWaitForDelete is like this :

func isWaitForDelete(apiService *service.MyService, id string, timeout time.Duration) (interface{}, error) {
	stateConf := &resource.StateChangeConf{
		Pending:    []string{"notyet"},
		Target:     []string{"done"},
		Refresh:    isRemoveRefreshFunc(apiService, id),
		Timeout:    timeout,
		Delay:      10 * time.Second,
		MinTimeout: 10 * time.Second,
	}

	return stateConf.WaitForState()
}

func isRemoveRefreshFunc(apiService *service.MyService, id string) resource.StateRefreshFunc {
	return func() (interface{}, string, error) {

		
		response, err := apiService.findServiceTargets(id)
		if err != nil {
			if response != nil && response.StatusCode == 404 {
				return nil, "done", nil
			}
			return nil, "done", fmt.Errorf("error getting response")
		}
		return response, "notyet", nil
	}
}

The refresh function is returning done but the wait function keeps on retrying 21 times and returns an error saying Error: couldn't find resource (21 retries)
