# error.ControlModeErrorKind.InvalidSubscriptionName

- **Module:** error.ControlModeErrorKind
- **Package:** libtmux
- **Language:** Rust
- **Kind:** constant

A subscription name was empty, or contained a colon.

tmux splits the subscription argument on its first colon, so a name
carrying one names something other than what was asked for and takes
the rest of the request with it. Refused here rather than sent,
because tmux accepts the result and reports no error.
