Same issue exists for @stoplight/json-schema-viewer would be nice if this could be merged

This PR allows @stoplight/elements to work with the default settings in the latest create-next-app.

Basically if moduleResolution is bundler in tsonfig.json (which is the default in create-next-app) you can't use @stoplight/elements without patching the package.
