Compile Error with V6.21.0

[stif]

Description
I have a Project which compiles fine with version 6.20.1 but fails with 6.21.0

Troubleshooter's report

1. The issue happens at compile time
2. The error is not in the list

Environment

• Microcontroller: ESP32
• IDE: PlatvormIO IDE v2.5.2 PlatformIO core 6.1.6

Reproduction code

constexpr size_t  jsonCapacity = JSON_OBJECT_SIZE(3) + JSON_ARRAY_SIZE(3) + 36;

void WebService::onWsEvent(AsyncWebSocket *server, AsyncWebSocketClient *client, AwsEventType type, void* arg, uint8_t *data, size_t len) {
  if (xSemaphoreTake(_smphr, 50) == pdTRUE) {
    if(type == WS_EVT_DATA) {
      Serial.print("Event Data received\n");
      AwsFrameInfo * info = reinterpret_cast<AwsFrameInfo*>(arg);
      if (info->final && info->index == 0 && info->len == len && info->opcode == WS_TEXT) {
        // the whole message is in a single frame and we got all of it's data
        StaticJsonDocument<jsonCapacity> doc;
        DeserializationError error = deserializeJson(doc, data, len); // <-line the compiler is complaining about

Sorry i was redirected via arduinojson website and did not see the same issue already exists. this seems to be a duplicate from #1897 . will close this issue..

Hi @stif,

Thank you very much for reporting this error.
Unfortunately, I don't manage to reproduce the error.
Can you provide an MCVE?

Best regards,
Benoit
