    }
});
// ===== or when using modules =====
import config from "devextreme/core/config";

    }
})

... or remove unnecessary SpeedDialAction widgets.

W1015

Occurs in the Scheduler when the range from the startDayHour to the endDayHour cannot be divided into even intervals because of the specified cellDuration.

To resolve this warning, calculate the range duration in minutes and find a cellDuration that divides the range duration without remainder. For instance, the range from 8 to 24 hours has a duration of 16 hours or 960 minutes. To specify the cellDuration, use any value that divides 960 without remainder.
