Unable to compile the elixir project

Getting this error when running mix deps.compile.
I tried rm -rf deps _build mix.lock, reinstalling elixir via asdf. I am running out of ideas now. Any help is appreciated.

===> Compiling src/rabbit_heartbeat.erl failed
src/rabbit_heartbeat.erl:22:39: syntax error before: ‘maybe’

rabbit_heartbeat.erl:20:2: type heartbeaters() undefined
rabbit_heartbeat.erl:32:13: type heartbeaters() undefined
rabbit_heartbeat.erl:38:13: type heartbeaters() undefined
rabbit_heartbeat.erl:49:21: type heartbeaters() undefined
rabbit_heartbeat.erl:50:22: type heartbeaters() undefined

** (Mix) Could not compile dependency :rabbit_common, “/Users/ranbirs/.asdf/installs/elixir/1.17.3-otp-26/.mix/elixir/1-17/rebar3 bare compile --paths /Users/ranbirs/workspace/carts-api-bk2/carts-api/_build/dev/lib/*/ebin” command failed. Errors may have been logged above. You can recompile this dependency with “mix deps.compile rabbit_common --force”, update it with “mix deps.update rabbit_common” or clean it with “mix deps.clean rabbit_common”

Currently the erlang AMQP client (and subsequent dependencies) don’t support OTP-27, the only option is to downgrade to OTP-26.

Here is the official link: Erlang Version Requirements | RabbitMQ

PS: I think there was somewhere a more detailed explanation on what it specifically breaks, but I cannot find it now.

maybe in Erlang is enabled by default only since OTP 27, earlier you need to use some flag to enable it, but I am not sure how you can do it in Mix for dependencies.

Hello @rsshek, welcome to the forums :slight_smile:

Can you upgrade to OTP 27? The maybe keyword will be supported out of the box.

Otherwise, can you try with this environment ERL_FLAGS='-enable-feature maybe_expr'?

I missed the Erlang version bit (serves me right for reading through the phone on the bed). Just upgrade to Erlang 27 and try it.
