Edge function Error : ERR_MODULE_NOT_FOUND on an installed module

[Britnell]

Hey team, I have an error I'm struggling to fix. I find similar MODULE_NOT_FOUNDS, but those seemed different.

• I am deploying my astro site on vercel
• Britnell/pushbullet
• turso hosted sqlite db
• building & running locally fine
• e.g. homepage is fine
• error happens on login api route , server crashes with :

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@libsql/client' imported from /var/task/.vercel/output/_functions/chunks/pages/app_m16mYN8C.mjs

  code: 'ERR_MODULE_NOT_FOUND'

I am using libsql/client to connect to turso db the endpoint is loading sql client :

import { createClient } from "@libsql/client/web";
export const turso = createClient({
  url: import.meta.env.TURSO_URL,
  authToken: import.meta.env.TURSO_TOKEN,
});

So it is failing to import an installed package. the build & install run fine, this works fine locally, I was using pnpm, so tried out with npm i too, but still had the same issue.

I was using bcrypt package which had problems running on edge, which i replaced with bcryptjs but libsql is a lightweight client suggested by turso, i feel like this should be able to work. Do you have any other debugging tips I can try?

In fact i just deployed the same project to Netlify and it works fine, so this must be the astro/vercel adapter. I don't know if you have access to my vercel deploy?
