Describe the bug I need to create nix infrastructure for my project. The final goal is a docker container that exposes an API endpoint.

below

• Build system x86_64-linux
• GHC version. version 9.0.2
• Haskell.nix version (or commit) used: 3a7f069ccc491c783a28429aa8bcb504f70dc62b

Steps To Reproduce

Steps for reproducing (try to minimise the size of the code base if possible). git clone git@github.com:SIDANWhatever/plutus-cborhex-automation.git cd plutus-cborhex-automation/example-validator niv init niv add input-output-hk/haskell.nix -n haskellNix niv update haskellNix ❌nix-build -A example-validator.components.exes.example-validator fix errors by adding --sha256 in cabal.project

Expected behavior docker load < $(nix-build docker.nix) exit code 0

Additional context the project is a Plutus rest API endpoint. I need to build a docker container for it.

Theory: I need to update tag in project.cabal, e.g. https://github.com/SIDANWhatever/plutus-cborhex-automation/blob/0cab0e61e235b168209e558aa950f652ce1f7cc0/example-validator/cabal.project#L103

Hypothesis: Nix will A(crash in next phase) or B(build)

Test: keep updating tags cabal.project, branch nix

I should test tag pairs for cabal.project in nix/sources.json

[aleeusgr]

Well, that is the famous nix annoying problem. Basically, you just put an empty string for the sha256 and nix will calculate it for you and print out in the error message.
