Bulk Messages Esp8266 - Subscriber Data not being saved

[Oseihie]

Hello @Bolukan and everyone,

I am trying the Bulk Messages example for the Esp8266. I flashed the code to the Esp8266 with no problem and was able to establish a communication between my bot from telegram and Esp8266.
After sending /start on telegram, i get a response with the commands and it is expected that the chat_id and name from telegram is saved in the json file. But when I send the request to see all subscribers, I get a response of null.

I have taken a look at the code but I cannot find what the issue might be.
Does anyone have an idea?

Replacing between //users.getOrCreateMember(chat_id, from_name); and subscribedUsersFile.close(); will solve the issue:-

if ((usersDoc.isNull()) && (subscribedUsersFile))
{
subscribedUsersFile.print("{"" + chat_id + "":" + """ + from_name + ""}" );
}
else
{
serializeJson(users, subscribedUsersFile);
users = usersDoc.as();
}
