After upgrading nix version from 2.28.4 -> 2.28.5 I am getting this error:

error:

Any known solution?

I had declared the flake input as github:yesodweb/yesod?dir=yesod-form and it seems that this notation has changed with the nix version update. https://github.com/NixOS/nix/pull/12801

So not related to haskell. Thanks for the quick reaction!

In reply to @robert:funklause.de
Is it possible to make it use hledger-lib_1_50?
