I have a typescript serverless project with serverless-webpack. It uses such modules as knex (sql query builder), pg, ioredis. Since these are designed to work server-side, there were some issues with bundling those with webpack, so I listed those as externals in webpack config.



Everything works but every time when packaging I get WARNING Could not determine version of module X for each of those.



Can someone explain me, what is the real underlying issue, which causes that and how can it be fixed to make things cleaner?

  • Did you actually check that module is in package.json dependencies. That might be coming from some other packages. I had the issue with express.js package. Later realised that it wasnt in package.json

  • I’m using a monorepo with lerna so it’s a bit more complicated. but it still should be resolved ok, all the dependencies are listed either in root or in local package. json
