I was wondering what happens if I try to connect to Notecard from two different terminals (one after the other). So, I wanted to disconnect from the Notecard and tried with the command “disconnect”.
The response was beautiful
{
"err": "JSON object expected: disconnect {io}"
}
However, trying with the offered command: “disconnect {io}” I got
{
"err": "cannot interpret JSON: string or '}' expected near 'io' {io}"
}
I seems that the initial error reponse is off - my interpretation was clearly bad
You can only send properly-formatted JSON commands through the REPL - so sending a string like disconnect
will return an error. If you want to disconnect from a terminal, you can click the USB button:

I failed to point you to my point
If one enters a command that is not a syntactically correct JSON object, the error message should be simple that (“JSON object expected”.
Getting back the error message JSON object expected: disconnect {io}
made me believe that I was a lot closer to the Disconnect command.
Got it - will definitely log this for review!
