Call to a member function getDisplayName() on null in ../detect_intent_texts.php:53

[fitwist]

It works fine in Google Cloud Shell, but when I try to reproduce it on my mac, I keep getting an error. The whole list of commands to reproduce it here: git clone https://github.com/GoogleCloudPlatform/php-docs-samples.git cd dialogflow gcloud config set project is-chatbot-gamma-wppq

gcloud auth login Authorized through Chrome window, status 'You are now logged in as [[email protected]]'

gcloud config set project test2-cpfv gcloud projects add-iam-policy-binding test2-cpfv --member="serviceAccount:[email protected]" --role="roles/owner" export GOOGLE_APPLICATION_CREDENTIALS="/Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/test2-cpfv-29ac10213682.json"

composer install

And the final one, intent detection throws an error: php dialogflow.php detect-intent-texts test2-cpfv "Заявка на абонемент"

The full output: `Session path: projects/test2-cpfv/agent/sessions/61557f051cb62 PHP Fatal error: Uncaught Error: Call to a member function getDisplayName() on null in /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/src/detect_intent_texts.php:53 Stack trace: #0 /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/dialogflow.php(56): Google\Cloud\Samples\Dialogflow\detect_intent_texts('test2-cpfv', Array, NULL, 'en-US') #1 /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/vendor/symfony/console/Command/Command.php(297): Closure->Google\Cloud\Samples\Dialogflow{closure}(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput)) #2 /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/vendor/symfony/console/Application.php(978): Symfony\Component\Console\Command\Command->run(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput)) #3 /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/vendor/symfony/console/Application.php(295): Symfony\Component\Console\Applicat in /Users/helenkapatsa/Repositories/php-docs-samples/dialogflow/src/detect_intent_texts.php on line 53

Line 53 of 'detect-intent-texts.php: $displayName = $intent->getDisplayName();

What can I do?
