Npm start stopped working after npm install --save forest-express-sequelize@latest

When I started Forest liana thru npm start to be able to access my database in forestadmin inside the development area I saw a message saying that a newer version of Liana exists and that I should do CLI npm install --save forest-express-sequelize@latest.

After doing this npm start started throwing an error. I thought I could undo what I did by unchecking the changes inside package.json and package-lock.json with git, but that doesn’t seem to help. I tried uninstalling forest-express-sequelize, but that didn’t work either. It’s really frustrating, could someone help me get out of this?

Expected behavior

After entering CLI npm start a node server should start just like this:

Actual behavior

When I enter npm start I get this instead:

git:(master) ✗ npm start

> ibiza-garden-houses@0.0.1 start
> node ./server.js

  if (!options.algorithms) throw new Error('algorithms should be set');
