Booking flow needs older version of node until we can upgrade and OLCI needs the current version otherwise the DELETE calls fail, here's how we can use multiple versions:
Refer: https://davidwalsh.name/upgrade-nodejs
Refer: https://github.com/tj/n
# node -v which is v0.10.37 for booking flow, EAS is using 4 and booking flow works
$ sudo npm cache clean -f
$ sudo npm install -g n
$ sudo n 0.10.37
$ sudo n stable
# Now you switch between versions but running, selecting and hitting enter
$ sudo n
