I’ve been trying to deploy my server on fly.io but I get this error while trying to run fly deploy --remote-only

=> ERROR [build 3/4] RUN npm ci                                                                                       0.9s

I’ve tried running the command with --legacy-peer-deps flag as well, but it doesn’t work. Is there a way to fix this. Thanks

Hi,

Looks like a code issue, rather than a Fly-specific one :thinking:. It seems that mongoose-currency has an old dependency, on mongoose 4. There is a pull request to update it but since that was 5 years ago it’s probably safe to assume that’s not going to happen:

It looks like someone has forked mongoose-currency to at least update to use mongoose 5. So you could try using that instead. That may resolve a conflict:
