I'm trying to run an app.js file with the command node app.js and the console is returning this error:
buffer.js:200
throw new ERR_INVALID_ARG_TYPE(
^
TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined
at Function.from (buffer.js:200:11)
at Object.<anonymous> (C:UsersAristophanesweb3_examplesapp.js:14:28)
at Module._compile (internal/modules/cjs/loader.js:707:30)
at Object.Module._extensions..js (internal/modules/cjs/loader.js:718:10)
at Module.load (internal/modules/cjs/loader.js:605:32)

at startup (internal/bootstrap/node.js:308:19)
at bootstrapNodeJSCore (internal/bootstrap/node.js:878:3)
Could anyone enlighten me as to how I could fix this error? Obviously it's something to do with an incorrect argument but I don't really know where to be looking.

The error message is pretty clear. The parameter is of wrong type,undefinedin this case, so you should debug your code to find out why it is not initialized. It should be atapp.js line 14.

What does 'col' refer to in this case?

That is for column.

OK but there is no column in line 14 of app.js
