I've been working through an
npx sst build
error with a Next/Tailwind starter blog for 3 nights worth of debugging and currently facing a
. I've been testing different packages, package versions, config files etc but haven't figured out how to crack this one yet

What's odd is that
npm run build
runs in the
directory; it's just when trying to execute via
where there's an issue... at this point I still can't say for certain that this is an SST issue, but I've scoured multiple threads/questions/issues to no avail. I'm also inexperienced with webpack which is being used in the starter ( Worst case scenario I am going to spin up a new Next frontend and incrementally add in pages/components while validating the build works via
npx sst build
. I have a separate SST app that's working with a Next frontend though that one has far fewer bells and whistles (which I'm suspecting is a potential issue besides my lack of familiarity w/ compiling)
I ended up using a less feature-rich template and
npx sst deploy
is working. It remans beyond me what the issue with the former template was, though I suspect it was likely a dependency/package issue.
Also expect this boils down to "I need to learn more about bundling" (@thdxr I know you're a fan of Vite) so start to ramp up here

Hey @Kevin Grimm, the
construct uses the serverless-nextjs library for bundling.
It bundles the Next.js app the same way as the
Give that construct a try, if it works, it’s probably an SST bug.

Cool thanks for this @Frank! I managed to get this deployed and integrated the additional features that weren't throwing any errors. But I'll take a look at this for future reference
There was some MDX bundling going on in the former that I think was the issue. Ended up just using
