unable to run mix coveralls because of MIX_ENV

[talhaazeemmughal]

i have defined it like this in config.exs:

{project_path, 0} = System.cmd("pwd", [])
project_path = String.replace(project_path, ~r/\n/, "/")

if Mix.env() == :dev do
  config :git_hooks,
    auto_install: true,
    verbose: true,
    hooks: [
      pre_commit: [
        tasks: [
          # clean the build
          {:mix_task, :clean},
          # Checking code formatting
          {:mix_task, :format, ["--dry-run", "--check-formatted"]},
          # Checking retired deps
          {:mix_task, "hex.audit"},
          # Security audit of deps
          {:mix_task, "deps.audit"},
          # Finding unused dependencies
          {:mix_task, "deps.unlock", ["--check-unused"]},
          # Verifying test coverage
          {:cmd, "mix coveralls"}
        ]
      ]
    ],
    project_path: project_path
end

mix coveralls doesn't execute if i pass it as {:mix_task, :coveralls} that is why i passed it as cmd but the issue is that some of the test cases fails while mix coveralls is getting executed in pre commit it is getting executed in dev environment. no test cases fail if i normally execute mix coveralls

even if i go with {:mix_task, :test, ["--trace"]} i still have the same issue.

P.s. I already tried what is mentioned in this issue
