UndefVarError: `execute_msg` not defined

Hello there,
I have a question.
I am new at Julia.
I am using JupyterNotebook with VSCode.
I try execute readline() command in Jupyter but its not working.
I got an error: UndefVarError: execute_msg not defined
But when i try this command on PowerShell,it worked.
I can not understand where is the problem?

That’s likely a bug, notebook support in VSCode is still a bit rough around the edges afaik. Might be worth filing an issue if it hasn’t been reported yet.

I understood thank you. So how can i report do? Where should i report?
