Hi, I'm using Kazoo's Puscher to send iOS notifications by apns4erl.
When the apns starts I got this error:

It seems that I've a OTP version less than 20 but I have the 22:

Erlang/OTP 22 [erts-10.7.2.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]

Anyone can help me please?

You will need to use an older version of apns4erl. We don't support OTP22 in the latest ones.

Actually… Our rebar.config says we do:

{minimum_otp_vsn, "19"}.

🤦🏻

It seems like the upgrade of gun introduced in #237 indeed had stuff that broke backwards compatibility. 🤷🏻

If it was me, I would just bump minimum_otp_vsn to 23 or something, but I'll defer to @ferigis for proper solutions to this.

I'm using apns-2.4.0 and gun-2.0.0-pre.2. Should I use apns4erl 1.0.6-final? I'll wait the @ferigis solution. Thank you very much.
