Programs with malfomed built-ins will not throw GUi-sided syntax errors

[slawrence100]

See this example program:

while True:
  bot.moooooooove_forward(100)

Expected Behavior: The Python error message box should show a syntax error for bot.moooooooove_forward(100).

Actual Behavior: The Base Station throws an error that is not caught and shown on the GUI.

I suspect that this is because the base station, not the bot itself, encounters this error; to my knowledge, we don't have a way to communicate this back to the client yet.

A possible fix would be to check the server's response code and use that to show a message on the GUI.
