Repeater field, inside Group field, cannot add entries programmatically

Hello all,

I’ve started using ACF for a project of mine that works as business directory. For each business (place) I want to register the working days and hours.

The structure I created is like this:

[Group Field] Name of the day (Monday, Tuesday, etc)
    [True/False Field] Open All Day
    [True/False Field] Closed All Day
    [Repeater Field] Time Entries
        [Time Picker Field. Display/Return Format H:i] Open Time
        [Time Picker Field. Display/Return Format H:i] Closing Time

Using code to create entries, I’ve managed to set the Open/Closed All Day fields, but I am not able to set the Time Entries.

I’ve tried several different formats of this code:

foreach ( $workingHours as $workingHour ) {
    $day = $workingHour->en;

    // Update all day open/closed fields
    update_field( "{$day}_all_day_open", $workingHour->allDayOpen, $post_id );
    update_field( "{$day}_all_day_close", $workingHour->allDayClosed, $post_id );

    if (
        true === $workingHour->allDayOpen ||
        true === $workingHour->allDayClosed
    ) {
        continue;
    }

    $time_entries = [];
    if ( ! empty( $workingHour->workingHours ) ) {
        foreach ( $workingHour->workingHours as $hour ) {
            $time_entries[] = [
                "open_time"    => $hour->opening,
		"closing_time" => $hour->closing,
            ];
        }
    }

    update_field( "{$day}_time_entries", $time_entries, $post_id );
}

Can someone help fix that issue?

— UPDATE —

I’ve tried also with the repeater field key as selector param and didn’t worked.

I’ve also tried the add_row like this:

add_row(
    $repeater_id,
    [
        "open_time"    => $hour->opening,
        "closing_time" => $hour->closing,
    ],
    $post_id
);

And still, doesn’t work.
