Problems encoding a nested map with poison
Can seem to encode this this json with Poison v4, using phoenix v1.4.1, getting error related to erlang.byte_size(..)
Any help would be appreciated.
** (Mix) Could not start application tradebot: Tradebot.Application.start(:normal, []) returned an error: shutdown: failed to start child: FTX.Client
** (EXIT) exited in: WebSockex.call(#PID<0.344.0>, {:text, {:ok, "{\"args\":{\"key\":\"fooooobaaarrrrbazzzzzzzz\",\"sign\":\"d10b5a67a1a941ae9463a60b285ae845cdeac1b11edc7da9977bef0228b96de9\",\"time\":\"1572290285343518000\"},\"op\":[108,111,103,105,110]}"}})
** (EXIT) an exception was raised:

Seems like you are encoding it just fine, but the result is a tagged tuple, {:ok, json}. You can either extract the json value from the tuple or use a “bang” version of the encoding command which returns the value directly.
