Hi, I have one resource and it has multiple tasks on same date. I have used eventrenderer to highlight the color orange if the dates overlap. It works fine for some task but shows green for others too.

using

eventRenderer(data) {
          const { eventRecord : task, resourceRecord, renderData } = data;
          const { eventStore } = task;
          // Highlight overlapping tasks within a resource
          if (!eventStore.isDateRangeAvailable(task.startDate, task.endDate, task, resourceRecord)) {
              renderData.eventColor = '#f4803a';
          }
          return task.name;
      },
    };
