I don't know if its the best way but I use this:
Instead of
{json, [{error,(ErrorList)}]}
I use:
{json, [{error,list_to_binary(ErrorList)}]}
This also seems to work:
{json, [{error,io_lib:write_string(ErrorList)}]}
I think the list_to_binary method cannot convert unicode characters
(http://www.erlang.org/doc/man/unicode.html) so for that case you could
need to use
{json, [{error,unicode:characters_to_binary(ErrorList)}]}
Someone please correct me if I am wrong.
Thanks,
Jitin
