It prints to the serial port, and what I get is what I expect. #include <ArduinoJson.h> DynamicJsonBuffer jbuffer; JsonObject& jsonResponse = jbuffer.createObject...

Just before I try to send the json i print it to the serial port, and it looks Ok, I added a '0' to the end of the json. static esp_err_t graph_data_handler (httpd_req_t *req) { char htmlRespons...
