`bg-primary-600` class does not exist error

I used the latest version of petal_compoents, 2.0.3 and set up the project as the docs explain. Here is the mix.exs deps/0 function:

defp deps do
    [
      {:phoenix, "~> 1.7.14"},
      {:phoenix_ecto, "~> 4.5"},
      {:ecto_sql, "~> 3.10"},
      {:postgrex, ">= 0.0.0"},
      {:phoenix_html, "~> 4.1"},
      {:phoenix_live_reload, "~> 1.2", only: :dev},
      # TODO bump on release to {:phoenix_live_view, "~> 1.0.0"},
      {:phoenix_live_view, "~> 1.0.0-rc.1", override: true},
      {:floki, ">= 0.30.0", only: :test},
      {:esbuild, "~> 0.8", runtime: Mix.env() == :dev},
      {:tailwind, "~> 0.2", runtime: Mix.env() == :dev},
      {:heroicons,
       github: "tailwindlabs/heroicons",
       tag: "v2.1.5",
       sparse: "optimized",
       app: false,
       compile: false,
       depth: 1},
      {:swoosh, "~> 1.5"},
      {:finch, "~> 0.13"},
      {:telemetry_metrics, "~> 1.0"},
      {:telemetry_poller, "~> 1.0"},
      {:gettext, "~> 0.20"},
      {:jason, "~> 1.2"},
      {:dns_cluster, "~> 0.1.1"},
      {:bandit, "~> 1.5"},
      {:petal_components, "~> 2.0.3"}
    ]
  end

When starting the application, I get this error:
