Application error on the second time

Error cef_ref_counted.h(325)] Assert failed: ptr_ != __null.

Hello I am new to CEF IPC communication I am trying to send a message from backend to javescript.

The program works well on first time run after make but the window appears blank on the second time.

Is there something I need to do in the function onContextReleased.

Here is the message sent from cefclient:

then the code in context Created

then the code in Excute function

.

the callback to the javascript:

const CefString& request = message->GetArgumentList()->GetString(5);
CefV8ValueList args;
args.push_back(CefV8Value::CreateString(request));

//excute javascript function
print_callback->ExecuteFunctionWithContext(print_callback_context_ ,NULL, args);
