Only done a quick review, I'm sure the rest of the team will do a more thorough review.

I've also noticed two files: airtable.old.js and ecostystem.old.js in the lib/ecosystem folder. Are they still being used or are they just on my local machine?

@kelvinkipruto then the column does not exist in airtable. Not a code problem
