Dialogflow Crash in AWS Deployment

Question

I deployed the same source code to AWS EC2 Linux instance, but it fails to display the response Text from dialogflow. I checked the conversation history in Dialogflow console, it shows both request and response correctly. However, the dialogflow client(PHP) seems crashes after calling the function "detectIntent". Unfortunately, got no way to find any logs.

Reinstalled Dialogflow Client Library

  $formattedSession = $sessionsClient->sessionName($agent, $agentSession->session_id);
  // Set Text Input
  $textInput  = new TextInput();
  $textInput->setText($text);
  $textInput->setLanguageCode($lang);

  // Set Parameters
  $optionalArgs = array();

  $queryInput = new QueryInput();
  $queryInput->setText($textInput);

  $response = $sessionsClient->detectIntent($formattedSession, $queryInput, $optionalArgs);

  $action = $response->getQueryResult()->getAction(); //The action name from the matched intent.

Answer 1

Hope the following experience helps others: For my case, the php version is not compatible with one of the Google API library. Hence it crashes somewhere we cannot capture. Solution: Uninstall PHP, and Install the compatible version of php.
