Here is your console

Error message

Here is your console

What it means

actionConsole is a built-in developer console endpoint that eval()s arbitrary code sent by the UI. After executing, it deliberately raises Exception('Here is your console') to terminate the request — this 'error' is the control-flow mechanism used to end the console response, not a real failure. It only occurs when the console feature is used (typically when enabled for local development).

Solutions

1. Treat this exception as the console's normal response terminator and read the computed result from the response body, not the exception
2. Disable/avoid exposing actionConsole in production; guard it behind authentication or remove the route
3. If wrapping requests in try/except, whitelist this message so it isn't reported as a failure
4. Upgrade or patch UiRequest so the console returns its result directly instead of raising

try:
    result = request_console(code)
except Exception as e:
    if "Here is your console" in str(e):
        pass  # expected control-flow termination, handle result normally
    else:
        raise

When it happens

Trigger: Calling the UiWebsocket/UiRequest console action (e.g. via the ZeroNet console UI or POSTing to the console route); the exception is raised intentionally after the eval loop returns its result.

Common situations: Developers using ZeroNet's interactive console during development; automated tests or scripts hitting the console endpoint; production deployments that accidentally left the console enabled.
