V_TEXT sensor throws Not valid message sub-type error

Hi folks,
in order to create some user specific sensors control, I tried to use the V_TEXT sensor, but even with the Notify example sketch in https://www.home-assistant.io/integrations/mysensors/ I get the following errors in HA:

Invalid <Message data="3;1;0;0;36;TextSensor1">: Not valid message sub-type: 36 for object value @ data['sub_type']. Got 36 not a valid value for object value @ data['payload']. Got 'TextSensor1'
Invalid <Message data="3;1;1;0;47;-">: Not valid message sub-type: 47 for object value @ data['sub_type']. Got 47 not a valid value for object value @ data['payload']. Got '-'
Invalid <Message data="3;1;2;0;47;">: Not valid message sub-type: 47 for object value @ data['sub_type']. Got 47

In all post I found, this is usually a version problem.
The used mysensors version is 2.3.2 according to the serial monitor of the node.
The mysensors integration in HA should be 2.3, but I don’t know how to check this, since the integration had been added via Settings / Devices & Services / Integration: “+ Add Intgeration” and I found no way to ask the integration about its version.
I would like to avoid a reinstallation of the mysensors integration, since I use a big amount of sensors already.

The log-information concerning this node (3) is as follows:

The used code from the Notify example sketch is:

/*
 * Documentation: https://www.mysensors.org
 * Support Forum: https://forum.mysensors.org
 */

// Enable debug prints to serial monitor
#define MY_DEBUG
#define MY_RADIO_NRF24

#include <MySensors.h>
#include <SPI.h>

#define SN "TextSensor"
#define SV "1.0"
#define CHILD_ID 1

MyMessage textMsg(CHILD_ID, V_TEXT);
bool initialValueSent = false;

void setup(void) {
}

void presentation() {
  sendSketchInfo(SN, SV);
  present(CHILD_ID, S_INFO, "TextSensor1");
}

void loop() {
  if (!initialValueSent) {
    Serial.println("Sending initial value");
    // Send initial values.
    send(textMsg.set("-"));
    Serial.println("Requesting initial value from controller");
    request(CHILD_ID, V_TEXT);
    wait(2000, C_SET, V_TEXT);
  }
}

void receive(const MyMessage &message) {
  if (message.type == V_TEXT) {
    if (!initialValueSent) {
      Serial.println("Receiving initial value from controller");
      initialValueSent = true;
    }
    // Dummy print
    Serial.print("Message: ");
    Serial.print(message.sensor);
    Serial.print(", Message: ");
    Serial.println(message.getString());
    // Send message to controller
    send(textMsg.set(message.getString()));
  }
}

The HA version is:
Home Assistant 2023.3.6
Supervisor 2023.03.2
Operating System 9.5
Frontend 20230309.1 - latest

Any suggestions are highly welcome!

“since the integration had been added via Settings / Devices & Services / Integration: “+ Add Intgeration” and I found no way to ask the integration about its version.”

I have added yesterday to HA the mysensors integration on the same page you have added. There was a mysensors version mentioned, it is 1.4 by default.

and V_TEXT supported after mysensors 2.0

I have looked around, but couldn’t find where is this setting stored after the integration added.

So if you didn’t change the 1.4 to your version when added the integration, it could be the cause.
