Hi @zaiste
Thanks for the report. I've done some testing and it seems the issue is related to using pnpm. It looks liek when we bundle the node modules for the functions, we're not including the symlinks, so the node_modules/next modules are just empty folders, even though all of the modules are actually there in node_modules/.pnpm. I'm going to open a separate issue on the zip-it-and-ship-it repo to handle this properly. In the meantime the only workaround I can suggest is to use npm or yarn.

I've updated the title to make it easier for other pnpm users to find. Once I find out how soon the fix is likely to be I may add a specific check in the plugin to ensure that at least it has a mroe helpful error message

@zaiste This was fixed in netlify/zip-it-and-ship-it#792, and in my fork now works with pnpm!
