Could not run deploy in Elixir 1.15

[Sgiath]

When running tailwind in this docker image hexpm/elixir:1.15.0-erlang-26.0.1-alpine-3.18.2 I get the following error:

** (UndefinedFunctionError) function :http_util.timestamp/0 is undefined (module :http_util is not available)
     (inets 9.0.1) :http_util.timestamp()
     (inets 9.0.1) httpc.erl:750: :httpc.handle_request/9

when I switch to hexpm/elixir:1.14.5-erlang-26.0.1-alpine-3.18.2 it runs correctly as expected.

Having the same issue here :)

Can you please provide a way to reproduce it? How are you starting Phoenix? In which environment? It feels like you are running in development inside Docker?

That error was happening for us during mix tailwind.install. It wasn't just the image, though, it was something I could also trigger locally.

We were running with Tailwind version 3.2.4 - after configuring Tailwind to use 3.3.2 instead the error went away.

Elixir/Erlang:

Erlang/OTP 26 [erts-14.0.1] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]

Elixir 1.15.0 (compiled with Erlang/OTP 26)

We are building our release inside a Docker container... It uses this base image (hexpm/elixir:1.15.0-erlang-26.0.1-alpine-3.18.2) and the dependency that is failing during compilation is tailwind. In our build it fails exactly in the step it executes:

mix tailwind.install

with the stacktrace provided as:

If you need more details happy to provide.

In our build it fails exactly in the step it executes: mix tailwind.install

This was the info I needed to reproduce it, thanks!

This also happens when running mix phx.gen.release --docker using Elixir 1.15.0.

You can use main and we shall have a new release soon. :)
