Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader

Question

I get the following error when trying to run yarn dev to launch a discord bot. I am using typescript. I have already tried using nvm to update the node js version. I even tried using lower versions of node.js all the way down to 16.20.2 with no success. I have the redis server running to the point where I use the redis-cli and it returns back with a PONG.

node:events:493
      throw er; // Unhandled 'error' event
      ^

Answer 1

So what I did to fix the error was add "type": "module", into the package.json file.
