where is postToTBD()?

is in another tab, see the code below

void postToTBD(JsonObject& data) {
  dataStr = "";
  data.printTo(dataStr);
  httpClient.beginRequest();
  httpClient.post(path);
  httpClient.sendHeader("Content-Type", "application/json");
  httpClient.sendHeader("Content-Length", data.measureLength());
  httpClient.sendHeader("Authorization", "Bearer "  + String(device_secret_key));
  httpClient.beginBody();
  httpClient.print(dataStr);
  httpClient.endRequest();
}

Try adding a httpClient.stop()

I still miss the code where you create and stop the HttpClient
