My issue was that I was running a PostCSS step as a part of my dev run script:

"dev:css": "yarn watch:css & next",
"watch:css": "postcss ./styles/index.tailwind.css -o components/.utilities.css -w",

I debugged by deploying another project and porting across my current project to it in chunks.

Agree that the error message is not helpful and could be improved.
