const newTask = record.create({
          type: record.Type.TASK,
          defaultValues: {
            title: taskName,//String
            company: entityId, //entity's internal id
            transaction: salesOrderId, //transaction's internal id
          },
        });
newTask.save();

 I got the following error but why this is happening?
