Unable to run on a phoenix project

Environment

• Elixir & Erlang/OTP versions (elixir --version):

Erlang/OTP 25 [erts-13.2.2.3] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit:ns]
Elixir 1.17.2 (compiled with Erlang/OTP 25)

• Which version of Dialyxir are you using? (cat mix.lock | grep dialyxir):

"dialyxir": {:hex, :dialyxir, "1.4.3", "edd0124f358f0b9e95bfe53a9fcf806d615d8f838e2202a9f430d59566b6b53b", [:mix], [{:erlex, ">= 0.2.6", [hex: :erlex, repo: "hexpm", optional: false]}], "hexpm", "bf2cfb75cd5c5006bec30141b131663299c661a864ec7fbbc72dfa557487a986"},

Current behavior

I have an existing phoenix project and I am trying to add dialyxir to it. I get the following error when trying to execute mix dialyzer

Expected behavior

• I would expect it to work

Not sure whether my code is causing this issue as I am not well versed in elixir but looking at the stack trace I would expect this to be related to the lib.

@lnenad is it possible you have a blank ignore file?

#405

Oh man you are right, I tried searching here, googling and AI and couldn't find the reason. Can I submit a PR to check for this situation as this just seems like a silly reason for it to bug out completely?

[jeremyjh]

@lnenad absolutely!

@jeremyjh done! #543
