I use mongodb in my project and it tells that can't find bson

(edited)

I use express in my api project and when i upload it to vercel, i received an error that can't find module "bson"

Cannot find module 'bson' Require stack:

/var/task/node_modules/mongodb/lib/bson.js
/var/task/node_modules/mongodb/lib/admin.js
/var/task/node_modules/mongodb/lib/index.js
/var/task/db.js
/var/task/server.js
/var/task/___now_launcher.js
/var/runtime/index.mjs Did you forget to add it to "dependencies" in package.json?

Hi , welcome to the Vercel Community!

Can you confirm if you have the https://www.npmjs.com/package/bson package installed and mentioned in the package.json file?

I'm sure that i add bson package to package.json

Hi , thanks for confirming. If you need more help, please share your public repo or a minimal reproducible example. That will let us all work together from the same code to figure out what’s going wrong.

Hi , thanks for sharing your repository. The project structure doesn't look correct to me for hosting on Vercel.

I recommend following this post about Express applications on Vercel.
