AWS Lex Lambda Response

Question

I have a lambda function connected to AWS Lex that calls an API key and gives the user a response with different articles, but since Lex's responce is in plaintext I am having issues getting each new article onto a new line and being to able highlight the links.

import json
import requests
def lambda_handler(event, context):
 try:
 # Log the event for debugging
 print("Received event:", json.dumps(event, indent=2))
 
 # Check if 'sessionState' and 'intent' are present in the event
 session_state = event.get("sessionState", {})
 intent = session_state.get("intent", {})
 # Get the intent name from the event
 intent_name = intent.get("name", "Unknown")
 if intent_name == "GetCyberNewsIntent":
 # API key and URL for NewsAPI
 api_key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
 base_url = "https://newsapi.org/v2/everything"
 query = "cybersecurity, cyber, Tech, IT" # Search keywords
 # Make a request to NewsAPI
 response = requests.get(f"{base_url}?q={query}&apiKey={api_key}")
 # Check if the API request was successful
 if response.status_code == 200:
 # Parse the JSON response from the API
 news = response.json()
 articles = news.get("articles", [])
 # Get the top 5 articles from the response
 top_articles = articles[:5]
 
 if not top_articles:
 # No articles found, set the response message
 message_content = "No recent cybersecurity news found."
 else:
 # Format the articles with line breaks (URLs in plain text)
 message_content = "\n".join(
 f"{i + 1}. {article['title']} - {article['url']}"
 for i, article in enumerate(top_articles)
 )
 else:
 # Handle API errors gracefully
 message_content = "Failed to fetch news. Please try again later."
 # Return the formatted response to Lex
 return {
 "sessionState": {
 "dialogAction": {
 "type": "Close" # Close the conversation
 },
 "intent": {
 "name": intent_name,
 "state": "Fulfilled" # Mark the intent as fulfilled
 }
 },
 "messages": [
 {
 "contentType": "PlainText", # Output the response as plain text
 "content": message_content
 }
 ]
 }
 else:
 # Handle unsupported intents
 return {
 "sessionState": {
 "dialogAction": {
 "type": "Close"
 },
 "intent": {
 "name": intent_name,
 "state": "Failed"
 }
 },
 "messages": [
 {
 "contentType": "PlainText",
 "content": f"Intent {intent_name} is not supported."
 }
 ]
 }
 except Exception as e:
 # Log and handle any unexpected errors
 print(f"Error: {e}")
 return {
 "sessionState": {
 "dialogAction": {
 "type": "Close"
 },
 "intent": {
 "name": "GetCyberNewsIntent", # Fallback to a valid intent
 "state": "Failed"
 }
 },
 "messages": [
 {
 "contentType": "PlainText",
 "content": f"An error occurred: {str(e)}"
 }
 ]
 }
