"{error, E} -> {json, [{errors, *list_to_binary*(E)}]}" is correct only
when u have 1 error, otherwise it will crash
Why u can's simply use binary strings?
[{fun()->length(UserPassword)>7 end,<<"Password length must at least 8!
<br>">>},
{fun()->length(UserEmail)>5 end, <<"Invalid E-mail address! <br>">>},
{fun()->boss_db:find(user_record,[{user_email,'equals',string:to_lower(UserEmail)},{id,'not_in',[Id]}])==[]
end, <<"This e-mail address is already registered! <br>">>}].
P.S. I'm just curious, what id stands for?
