I’m trying to release a personal project to Fyi.io, but when I run fly launch I got the below error:

(SyntaxError) invalid syntax found on nofile:1:1:

Here’s the Erlang and Elixir versions I’m using:
Erlang/OTP 25
Elixir 1.16.2

And here’s the list of deps:

  {:phoenix, "~> 1.7.9"},
  {:phoenix_html, "~> 3.3"},
  {:phoenix_live_reload, "~> 1.2", only: :dev},
  {:phoenix_live_view, "~> 0.19.0"},
  {:floki, ">= 0.30.0", only: :test},
  {:phoenix_live_dashboard, "~> 0.8.0"},
  {:esbuild, "~> 0.7", runtime: Mix.env() == :dev},
  {:tailwind, "~> 0.2.0", runtime: Mix.env() == :dev},
  {:swoosh, "~> 1.3"},
  {:finch, "~> 0.13"},
  {:telemetry_metrics, "~> 0.6"},
  {:telemetry_poller, "~> 1.0"},
  {:gettext, "~> 0.20"},
  {:jason, "~> 1.2"},
  {:plug_cowboy, "~> 2.5"},
  {:phoenix_ecto, "~> 4.0"},
  {:credo, "~> 1.7", only: [:dev, :test], runtime: false},
  {:horde, "~> 0.9.0"},
  {:excoveralls, "~> 0.18", only: :test}

I set the environment to PROD and ran mix compile and then mix phx.gen.release, but I didn’t get the error by doing that.

Does anyone know how to proceed?
Thanks in advance!
