Turborepo, build package, nodeFetch is not a function

I'm working on an app, which will go into production testing within 14 days.

I'm running turborepo and I have drizzle / turso running in a separate workspace. Which gets built and used by an application.

When I do not build the package and the gateway in package.json is "main": "/src/index.ts",. Everything works fine.

However, when I build it to simulate production AND to get the types when I import the package. I get the following:

 TypeError: nodeFetch is not a function

Let me know if you require a MVP to take a look.

Start by reproducing the failure with the Turborepo package built and imported through packages/db/dist/index.cjs, then inspect the stack locations in @libsql/isomorphic-fetch/node.cjs and @libsql/hrana-client/lib-cjs/http/stream.js. Done means the built package can be imported and used without the “nodeFetch is not a function” error or the missing dist/index.cjs error.
