{(estimates || []).map(e => {

        x =>
            x.identifier ===
                        e.cardIdentifier

e.cardIdentifier <- this maybe UNDEFINED

    )!;
    return this.renderCard(
        card,

card <- this too undefined, and next I see white screen

        false,
        false,
        (canPerformAdminActions &&
            this.doCommitCard.bind(
                this,
                card
            )) ||
            undefined

Maybe something like this?

x.identifier ===
(e.cardIdentifier || '?')
