const VariantPoolList.hpp:98 (poolIndex < count_ #2034Description
I cannot use the the Arduino Json Troubleshooter since the issue happens when building a json document, when allocating memory.
I do not use any custom allocator.
Board is the standard ESP32 NodePCU Dev Kit from AZ-Delivery.
I have no idea what to do or how to troubleshoot this...
How I am using the JsonDocument:
JsonDocument doc;
// adding fields
// check if overflowed(doc) is true
// if yes, I am calling send(...) which serialises and clears the doc
// then the caller continues to fill the doc for the next websocket batch
// check if overflowed(doc) is true
// etc...
void ESPDash::send(AsyncWebSocketClient* client, JsonDocument& json) {
const size_t size = measureJson(json);
AsyncWebSocketMessageBuffer* buffer = _ws->makeBuffer(size);
if (!buffer) {
json.clear();
return;
}
serializeJson(json, buffer->get(), size);
#ifdef DASH_DEBUG
Serial.printf("T [DASH] client=%u, measureJson=%u\n", (client == nullptr ? -1 : client->id()), size);
#endif
if (client != nullptr) {
client->text(buffer);
} else {
_ws->textAll(buffer);
}
json.clear();
}
bool ESPDash::overflowed(JsonDocument& json) {
#if ARDUINOJSON_VERSION_MAJOR == 7
return measureJson(json) > DASH_JSON_SIZE;
#else
return json.overflowed();
#endif
