Error Code Troubleshooting

• ERR-001 Database Connection Failed

  Description:

  The system was unable to establish a connection to the database server. This could be due to network issues, incorrect credentials, or the database server being offline.

  Possible Causes:

  • Database server is not running.
  • Incorrect database hostname or port.
  • Firewall blocking the connection.
  • Invalid database username or password.
  • Network connectivity issues.

  Resolution Steps:

  1. Verify that the database server is running and accessible.
  2. Check the database connection string for accuracy (hostname, port, database name).
  3. Ensure that any firewalls between the application and the database are configured to allow traffic on the database port.
  4. Confirm that the database credentials are correct and have the necessary permissions.
  5. Test network connectivity from the application server to the database server using tools like `ping` or `telnet`.
• ERR-002 File Not Found

  Description:

  A required file could not be located at the specified path. This often happens when a file is moved, deleted, or the path is misspelled.

  Possible Causes:

  • File has been deleted or moved.
  • Incorrect file path specified in configuration or code.
  • Permissions issue preventing access to the directory.

  Resolution Steps:

  1. Verify the file's existence and its location.
  2. Double-check the file path for any typos or inconsistencies.
  3. Ensure the application has read permissions for the directory containing the file.
  4. If the file is dynamically generated, check the process that creates it.
• ERR-003 Invalid Input Data

  Description:

  The data provided to the system does not meet the expected format or constraints. This is a common validation error.

  Possible Causes:

  • Missing required fields.
  • Incorrect data types (e.g., text where a number is expected).
  • Values outside of acceptable ranges.
  • Malformed data structure (e.g., JSON or XML).

  Resolution Steps:

  1. Consult the API documentation or user guide for the expected data format.
  2. Review the input data for any missing or malformed fields.
  3. Ensure all required fields are present and correctly formatted.
  4. Validate data types and value ranges against specifications.
  5. If using an API, check the request payload carefully.
• ERR-004 Authentication Failed

  Description:

  The provided credentials (username, password, API key) are invalid or insufficient for the requested operation.

  Possible Causes:

  • Incorrect username or password.
  • Expired or invalid API key.
  • User account locked or deactivated.
  • Insufficient privileges for the action.

  Resolution Steps:

  1. Verify the username and password are correct.
  2. Ensure the API key is valid and has not expired.
  3. Check the status of the user account.
  4. Confirm that the user has the necessary permissions for the requested resource or action.
  5. If troubleshooting an API, ensure the authentication headers are correctly formatted.
