(Jason.DecodeError) unexpected byte at position 0: 0x3C ("<") crashed my program #40
Description
I built a telegram bot api proxy with cloudflare worker based on the open source project Telegram-API-Proxy, and when the proxy layer returned a message in non-json format, Jason.decode! crashed the whole program.
error throw in：
telegex/lib/telegex/caller/adapter.ex
Line 46 in cc8a77c

Last message (from RssGenericI18nBot.Telegram.TelegramPoller.Supervisor): :fetch_meI tried adding some debugging information to adapter.ex, and found that sometimes the proxy return [info] Would decode Telegram Response: error code: 520 file=lib/telegex/caller/adapter.ex line=46 application=telegex
@spec struct_response(String.t() | map) :: Response.t()
def struct_response(json) when is_binary(json) do
Logger.info("Would decode Telegram Response: #{json}")
data = Jason.decode!(json, keys: :atoms)
struct(Response, data)
endAre there any good ways to deal with it？
