One common issue developers might encounter while using the Langraph Agentic Framework is the AGF-012: Database Connection Error. This error typically manifests when the framework fails to establish a connection to the specified database. Users may notice application downtime or inability to access data-driven functionalities.

Exploring the Issue

Error Code: AGF-012

The error code AGF-012 indicates a database connection problem. This can occur due to various reasons, such as incorrect database credentials, misconfigured connection settings, or network issues preventing access to the database server.

Common Causes

  • Incorrect database URL or port.
  • Invalid username or password.
  • Network firewall blocking database access.
  • Database server downtime or unavailability.

Steps to Resolve the Database Connection Error

Step 1: Verify Database Credentials

Ensure that the database username and password are correct. You can test these credentials by attempting to log in directly to the database using a database client tool.

Step 2: Check Connection Settings

Review the database connection URL, port, and other settings in your configuration file. Ensure they match the database server's actual settings. For example, the connection string might look like:

jdbc:mysql://localhost:3306/your_database_name

Step 3: Test Network Connectivity

Ensure that your application server can reach the database server. You can use the ping command or telnet to test connectivity:

ping your_database_server_addresstelnet your_database_server_address 3306

Step 4: Review Firewall Settings

Check if there are any firewall rules blocking access to the database server. Ensure that the necessary ports are open for communication.
