Използване на Async с MongoDb за попълване на документи за събиране по ред

вашият insertRowInBLD функцията трябва да върне Promise екземпляр вместо undefined както сега. Async.series се предава масив от undefined .

Това.

function fillBLD() {
    async.series(
        [
            insertRowInBLD('R01', 'Disclosure of data due to deliberate action by internal actor', 'E. Not significant', 'Partially effective', 'Low', '', '', '', ''),
            insertRowInBLD('R02', 'Corruption of data due to deliberate action by internal actor', 'E. Not significant', 'Partially effective', 'Low', '', '', '', ''),
            insertRowInBLD('R03', 'Unavailability of data due to deliberate action by internal actor', 'E. Not significant', 'Partially effective', '', '', '', '', ''),
            insertRowInBLD('R04', 'Disclosure of data due to attack of the communications link by internal/external actor', 'E. Not significant', 'Partially effective', 'Low', '', '', '', ''),
            insertRowInBLD('R05', 'Corruption of data due to attack of the communications link by internal/external actor', 'E. Not significant', 'Partially effective', 'Low', '', '', '', ''),
        ]
    );
}

всъщност е това.

function fillBLD() {
    async.series(
        [
            undefined,
            undefined,
            undefined,
            undefined,
            undefined
        ]
    );
}
