Build fails with Could not deduce ... errors

[omefire]

I have included cardano-prelude as a dependency in my project's cabal.project file: https://github.com/omefire/api-server/blob/main/cabal.project

However, when I try to build the project with cabal build, I always end up getting this error:

• I am on a mac
• How do I get past this issue?

Having same issue

[coot]

it seems like one of the packages is using newer version that is supported by cardano-prelude. If you are using cabal you could try to use the same index-state as in cabal.project in this repo.

[zmrocze]

anyone knows which dependency is at fault and has the incorrect bound?
