{aborted, {bad_type, {...} } on mnesia:write/3

Question

Supressing irrelevant code, i've the following:

% somefile.erl

-record(task, {description, date, completed = false}).

init() ->
  {atomic, _} = mnesia:create_table(task, [{attributes, record_info(fields, task)}]).

In other file, where the {aborted, {bad_type, {}}} is ocurring:

-record(task, {id, description, date, completed = false}).

create_task(Req, State) ->
    Task = create_task_record(),
    Transaction = fun() -> mnesia:write(task, Task, write) end,
    {atomic, _} = mnesia:transaction(Transaction),
    % ...

When i'm running the code, in the line {atomic, _} = mnesia:transaction(Transaction), i'm receiving the error {aborted, {bad_type, {task, ...}}}.

Answer 1

After hours trying to find, the problem here is in the record task definition. I wasn't using the hrl to share definitions, so i have the definition where i was using it, because of this, in one file the definition was missing the id attribute, so i was having different types.
