"make all" exited with code 0. Shutting down Netlify Dev server

BTW, I also read:

a) Build commands exit with code 0 but site doesn't finish deploying and times out
b) Cannot run netlify dev locally

You’re welcome to trigger a build, as was suggested for (a), but since my issue is with the dev build I assume that won’t help you.

b) seemed to be solved by adding a framework, but since I’m just using make and bash scripts to build my html, I guess that isn’t relevant either.
