Repro: snowpack bug on json imports for some mount configs.
The problem:
JSON import specs that start with / (not with ./ or ../) fail. This is because CWD (or root path) is used, and mount is not used, which leads to wrong fs paths.
cd apps/app1
npx snowpack dev
or...
npx snowpack build
And just check out network panel in chrome.

Instead, maybe do something like...

And that's about it.
