hi @wfjm thanks for the issue 👍. Can you share the exact error message you are receiving?

[wfjm]

The point is that no error message is given, invalid flags are simply ignored. This is a bit unusual for CLI tools, usually they complain about invalid flags. Good practice to catch typos.

that's fair, we've had user requests to explicitly remove the error when providing flags that aren't expected. They basically get ignored silently.
