Node.js Error: connect ECONNREFUSED ::1:80 - Unhandled Promise Rejection

This error message indicates that there was a problem connecting to the server at localhost on port 80 (ECONNREFUSED ::1:80). \n\nThe warning is telling you that there was an unhandled promise rejection, meaning that a promise was rejected but no catch block or .catch() method was used to handle the rejection. This can lead to unexpected behavior in your code.\n\nTo debug this issue, you can use the --trace-warnings flag when running your Node.js script to get more information about where the warning was created. Additionally, you can use the --unhandled-rejections=strict flag to terminate the Node.js process on unhandled promise rejections.\n\nIt is also worth noting that unhandled promise rejections are deprecated and, in the future, they will terminate the Node.js process with a non-zero exit code. It is best practice to always handle promise rejections with a catch block or .catch() method to avoid these warnings and potential issues.
