Error adding task into task list

[caumons]

Every time I try to add a new task in a task list the following error is shown at the bottom of the page: An unexpected error occurred. If this keeps happening, please contact a site administrator

If I check the browser's console log I can see the following stack trace:

It seems that the response param at onEditTaskSubmitted function is undefined and when trying to access response.reloadTask crashes (response.reloadLists would also crash).

We're using Humhub 1.2.4 and the Tasks Module version is 1.1.13

The same happens in mine, has anyone managed to solve it?
