ERR_INVALID_CALLBACK Upon Starting App

[ChrisHuffman]

Upon starting the app, I will see several feed items being loaded through the console, but before I can even check it out on localhost, the app stops and I get the following error:

fs.js:129
throw new ERR_INVALID_CALLBACK();
^

TypeError [ERR_INVALID_CALLBACK]: Callback must be a function

@ChrisHuffman --

I just downloaded the current version of River5 and it runs here with the latest version of Node downloaded following the instructions on this page.

https://github.com/nodesource/distributions#debinstall

You must be running a later version that no longer supports a feature that River5 is using.

I am running Node v11.6.0.

You can tell what version you're running with this command.

node --version
