Add/Remove target location of campaign

Hello Team,

Goal: To add/remove target location in campaign

I want to add location in campaign target location. To achieve this I am using this code:



$campaignCriterionService =
        $user->GetService('CampaignCriterionService', ADWORDS_VERSION);
        $user->SetClientCustomerId(base64_decode($ajaxData['clientId']));
        //echo '<pre>';
        //print_r($ajaxData);die();
        $campaignCriteria = array();
       
        // Create locations. The IDs can be found in the documentation or retrieved
        // with the LocationCriterionService.
        $location = new Location();
        $location->id = intval($ajaxData['Target']);   // location id e.g. 2840 etc.    
       
        //$campaignCriteria[] = new CampaignCriterion($ajaxData['CampaignId'], null, $location);
       
        $campaignCriteria[] = new CampaignCriterion(intval($ajaxData['CampaignId']), null, $location);

       
        // Create operations.
          $operations = array();
          foreach ($campaignCriteria as $campaignCriterion) {
            $operations[] = new CampaignCriterionOperation($campaignCriterion, 'ADD');
        }
       
        // Make the mutate request.
        $result = $campaignCriterionService->mutate($operations);

But this giving me following error:

<br />
<b>Fatal error</b>:  Uncaught SoapFault exception: [soap:Server] [EntityNotFound.INVALID_ID @ operations
[0].operand.campaignId; trigger:'CampaignId: 254533954'] in /home/bergstromdev/public_html/Google/Api

Kindly guide me how I can escape these errors. I pick this code from examples provided in the php library
