Uncomment this one when deploying Novu in the local environment

Based on the error message and the environment file you've provided, it appears that there's an issue with the MongoDB connection string. The error suggests that the DNS resolution for the MongoDB cluster is failing. Let's address this issue step by step:
1. First, the error you're encountering is:
This error indicates that the DNS resolution for your MongoDB Atlas cluster is failing. (1)
2. In your environment file, you have the following MongoDB connection string:
3. The issue might be related to DNS resolution within your Docker container. Here are a few things you can try:
a. Ensure that your Docker container has proper network connectivity and can resolve DNS queries.
b. Try using the MongoDB connection string without the SRV record. Replace
mongodb+srv:// with mongodb:// in your connection string. c. If you're running this in a local development environment, you might need to adjust your Docker network settings or use a different DNS server.
4. To troubleshoot further, you can try the following:
a. Verify that you can ping or nslookup the MongoDB host from within your Docker container.
b. Check if there are any network restrictions preventing your Docker container from accessing external services.
c. Ensure that the MongoDB Atlas cluster is properly configured and accessible from your network.
5. If the issue persists, you might want to consider using a local MongoDB instance for development purposes. You can update your docker-compose.yml file to include a MongoDB service and update the MONGO_URL in your .env file accordingly. (2) (1)
