ESP32 - Data Event on Serial2 only one event

The problem persists.Here is a simpler example with my console return. We notice that the event on the serial reception does not work anymore after a writing.

Code Esp32 - Esrpuino

Serial2.setup(9600, {rx:D16,tx:D17});

Serial2.on('data', function(data) {
  console.log("<SERIAL> "+data.toString());
  Serial2.write("Hello from Esp32\n");
});

Console

TEST_1
SEND:TEST_1
RECV:Hello from Esp32
TEST_2
SEND:TEST_2
TEST_3
SEND:TEST_3

Can you help me ?
