Ensure compatibility for devs with the latest NodeJS versions

We seem to run into problems with NodeJS v10 and NodeJS v17.4

NodeJS v17.4 gives this error when trying to compile:
```
error TS2571: Object is of type 'unknown'.
```

For now, NodeJS v14 seems to work fine though.


# Definition of Done

- [ ] Dev Docs updated to use a newer version of NodeJS
- [ ] Code updated to work with a newer version of NodeJS
