Argument error with elixir 1.11.4

I updated elixir to version 1.11.4, and since then I have the following error:

** (ArgumentError) argument error

Hey, thanks for reporting this. Looks like you're running into this issue, which in turn is due to a breaking change in OTP that's being discussed here.

I've subscribed to those threads; once they agree on a solution they'll hopefully release new versions of both OTP and gen_smtp, which should solve your problem as well. Until then, the easiest thing to do may be either to use gen_smtp's temporary patch or to downgrade your Elixir installation – sorry!

Hi,

Thank you for your quick reply !

For the moment, I have downgraded the version of elixir because I don't have the need to use the latest version.
