Dialogflow v2 PhP Set Context in Detect Intent

Question

I am trying to set the context with the following code.

  $text = "Some Text";
    $sessionsClient = new SessionsClient(array('credentials' => base_path('/google-cloud.json')));
    $session = $sessionsClient->sessionName('[project-id]', uniqid());
    $textInput = new TextInput();
    $textInput->setText($text);

    $queryInput = new QueryInput();
    $queryInput->setText($textInput);
    $textInput->setLanguageCode('en-US');

    $queryParams = new QueryParameters();
    $contextInput = new Context();
    $contextInput->setLifespanCount(1);
    $contextInput->setName('Input_Text');
    $queryParams->setContexts(array($contextInput));
    $optionalsParams = array('queryParams' => $queryParams);

    $response = $sessionsClient->detectIntent($session, $queryInput, $optionalsParams);
    $queryResult = $response->getQueryResult();
    $queryText = $queryResult->getQueryText();
    $intent = $queryResult->getIntent();
    $displayName = $intent->getDisplayName();
    $confidence = $queryResult->getIntentDetectionConfidence();
    $fulfilmentText = $queryResult->getFulfillmentText();

    return [
        'data' => [
            'success' => true,
            'text' => $text,
            'queryResult' => $queryResult,
            'queryText' => $queryText,
            'intent' => $intent,
            'displayName' => $displayName,
            'confidence' => $confidence,
            'fulfilmentText' => $fulfilmentText,
        ]
    ];

Receiving the following error

{ "message": "com.google.apps.framework.request.BadRequestException: [ResourceName error] Path 'Input_Text' does not match template 'projects\/{project_id=*}\/locations\/{location_id=*}\/agent\/environments\/{environment_id=*}\/users\/{user_id=*}\/sessions\/{session_id=*}\/contexts\/{context_id=*}'.", "code": 3, "status": "INVALID_ARGUMENT", "details": [] }

Has anyone got it working? There is no mention of passing Context through request in docs or in sample code.

Solved, need to format the intent name with Google\Cloud\Dialogflow\V2\ContextsClient::contextName before using setIntent

Working Code

   $text = "Some Text";
    $project_id = '[project-id]';
    $session_id = uniqid();
    $sessionsClient = new SessionsClient(array('credentials' => base_path('/google-cloud.json')));
    $session = $sessionsClient->sessionName($project_id, $session_id);
    $textInput = new TextInput();
    $textInput->setText($text);

    $queryInput = new QueryInput();
    $queryInput->setText($textInput);
    $textInput->setLanguageCode('en-US');

    $queryParams = new QueryParameters();
    $contextInput = new Context();
    $contextInput->setLifespanCount(1);
    $contextInput->setName(Google\Cloud\Dialogflow\V2\ContextsClient::contextName($project_id, $session_id, 'input_text'));
    $queryParams->setContexts(array($contextInput));
    $optionalsParams = array('queryParams' => $queryParams);

    $response = $sessionsClient->detectIntent($session, $queryInput, $optionalsParams);
    $queryResult = $response->getQueryResult();
    $queryText = $queryResult->getQueryText();
    $intent = $queryResult->getIntent();
    $displayName = $intent->getDisplayName();
    $confidence = $queryResult->getIntentDetectionConfidence();
    $fulfilmentText = $queryResult->getFulfillmentText();

    return [
        'data' => [
            'success' => true,
            'text' => $text,
            'queryResult' => $queryResult,
            'queryText' => $queryText,
            'intent' => $intent,
            'displayName' => $displayName,
            'confidence' => $confidence,
            'fulfilmentText' => $fulfilmentText,
        ]
    ];
