I'm relatively new to vercel and in the last month I've spent more hours than I care to admit debugging random errors because the vercel build logs are essentially useless.

Today's fun came from pushing a branch up to vercel, thinking it was using the Development environment and it's associated env vars. Only to find out later that it was being built under the Preview environment, but that my Preview environment was missing a couple variables. My Preview (staging) environment, which I configured to for actual preview builds was setup correctly.

However, if you peek those logs, they have absolutely nothing to do with missing env vars, random pages & api routes complaining about not being able to access replace of undefined (the method replace DNE in any of those pages).

Vercel build logs provide about as much useful information for tracking down bugs as the Iranian radar system

Is there everyone else's experience as well? Are there tools that can be installed to pull more useful information out?
