For bcrypt_elixir version 1.0, you need to be using Erlang 20.

Downgrade to bcrypt_elixir version 0.12, and there should be no problem.

Let me know if that works.

@riverrun Thanks for quick response. I am out now. I will let you know after either downgrading bcrypt_elixir or upgrading the erlang and testing.

@riverrun Glad it worked when I upgraded to erlang 20.0 Thanks 💐

According to @riverrun explained about the issue following his hints I Upgrading to erlang 20.0 It is working as expected now. Thanks to @riverrun for quick response.

Glad to hear you got it working. I'm just working on improving the error message now.

@riverrun error message with clear information what causing the error would be nice.... Glad to hear that you are working on that...
