unable to resolve dependency tree

Hi I tried to run npx create-sourcebit with the options: contentful, transform-assets, and next and get the following error:

@adnjoo Did you manage to resolve this error? I'm getting the same thing and there's nothing online on how to fix it.

Looks like the old version of sourcebit-target-next (v0.5.2) had Next.js v9 peer dependency on Next.js.
Updated sourcebit-target-next to v0.6.2, it is now using Nextjs v10 as peer dependency.
