Deployment error on Vercel

[NathanLandsX]

Hi, I've added this template to an existing code base. Locally everything works fine and pulls in all of my posts etc. but when I try to push to Vercel, I get this error:
--error Failed to parse URL from undefined/ghost/api/v3/content/posts/?key=undefined&include=authors,tags

Hi, sorry for the delayed answer, I guess you solved it on your own.

For other people seeing this issue please check your Vercel project settings, "Environnement Variables" tab:
