Getting issue while building the haskell project via 'cabal build' command

[__1] trying: base-4.16.3.0/installed-4.16.3.0 (dependency of
project_name)
[__2] next goal: aeson (dependency of project_name)
[__2] rejecting: aeson-2.1.0.0 (conflict: project_name => aeson==1.5.6.0)
[__2] skipping: aeson-2.0.3.0, aeson-2.0.2.0, aeson-2.0.1.0, aeson-2.0.0.0

excluded by constraint '==1.5.6.0' from 'project_name')

The report only includes output from the `cabal build` dependency solver, showing conflicts among `base`, `ghc-prim`, and `aeson` constraints. Start by reproducing the build with the same project constraints and inspect the package configuration; done means the conflicting dependency requirements and a reproducible resolution or required project change are identified.
