@clin1234 Unfortunately building the package of this project with GHC 9.12.1 is not supported yet.
For dhall-toml you may want to try building it with e.g. GHC 9.8.4.
Also, the different stack.yaml files found at the root of this repository might be helpful.

While it is a bit too soon to move to GHC 9.12 for general use, FWIW all that's actually needed, for the main library at least, is --allow-newer=dhall:template-haskell.
