This project demonstrates issue with stack v2.3.1
Stack ignores shapshot.yaml configuration that uses git location of typed-encoding-0.4.9.0 dependency
and suggest to add older Hackage version as dependency

DEPRECATED: The package at Repo from git@github.com:rpeszek/typed-encoding, commit e938fcb63f5f18bf1dda5e5aad0ac0be660b18d1 does not include a cabal file.
Instead, it includes an hpack package.yaml file for generating a cabal file.
This usage is deprecated; please see https://github.com/commercialhaskell/stack/issues/5210.
Support for this workflow will be removed in the future.
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for test-stack-snapshot-0.1.0.0:
typed-encoding needed, but the stack configuration has no specified version (latest matching version is 0.4.2.0)
needed since test-stack-snapshot is a build target.
Some different approaches to resolving this:
* Recommended action: try adding the following to your extra-deps in /mnt/data/proj/hh_code/test-stack-snapshot/stack.yaml:
- typed-encoding-0.4.2.0@sha256:8b92de5f695ccf295990365e9f46bd2d904ec15e1c9c3e0578e4eb56b1ee27ff,5217
Plan construction failed.
This builds the project just fine:
STACK_YAML=stack-works.yaml stack build
Note, there seems to be no problem with projects which are not not in Hackage at all (this project adds dag-check dep which is exactly like that).
Seems to be a regression? See commercialhaskell/stack#3714
