Callback during tb.loop causes Guru Meditation Error #202
Description
PlatformIO project for ESP32 using Arduino framework.
ThingsBoard 0.12.2
I noticed an issue where the ESP32 would crash if a Shared Attribute or RPC callback is received while we are uploading telemetry. I have looked through all the open and closed issues for the Thingsboard CLient SDK but could not find any relevant solutions.
I get the following error output over UART:
2024-05-16 11:29:53 Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

The following function is called from a task to send the telemetry:
//Function to send a specific PompStasie status updates to thingsboard
void updateThingsboardStatus(BesproeingsPunt* endNode) {
//Send all the telemetry data of the specific pompstasie
String telemetryKey = endNode->get_uuid() + "_pressure1";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->pressure1);
telemetryKey = endNode->get_uuid() + "_pressure2";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->pressure2);
telemetryKey = endNode->get_uuid() + "_batteryVoltage";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->batteryVoltage);
telemetryKey = endNode->get_uuid() + "_actuator0_state";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->valveState);
telemetryKey = endNode->get_uuid() + "_lastTransmission";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->lastTransmission);
telemetryKey = endNode->get_uuid() + "_connectivityStatus";
tb.sendTelemetryData(telemetryKey.c_str(), endNode->isOnline());
}
With the main loop then being used to call tb.loop:
void loop()
{
//Main loop runs at lowest priority (Priority = 0)
if (!OTA_FLAG){
// Process received Thingsboard messages messages
if (tb.loop()) {
thingsboardDownlinkInProgress = false;
}
thingsboardConnect();
}
}
