Invalid 'opt' in ShowForm

Error message

Invalid 'opt' in ShowForm

What it means

The input component's show form mirrors the completion one: ShowForm::try_from takes an attached "opt" value (an InputOpt) from the Action. An action without that attachment fails with "Invalid 'opt' in ShowForm". FromLua/IntoLua are intentionally unsupported, so the form must come from Rust-side construction or a properly populated action.

Solutions

1. Construct the form directly: ShowForm::from(input_opt)
2. When emitting an action, always attach the option with .with_any("opt", opt)
3. Audit for earlier take_any("opt") calls on the same action

Example fix

// before
let form = ShowForm::try_from(action)?; // action has no "opt"

// after
let form = ShowForm::from(opt); // construct directly from InputOpt

// Ensure the action carries the option before conversion:
ensure!(action.get::<InputOpt>("opt").is_some(), "show action requires an attached opt");
let form = ShowForm::try_from(action)?;

When it happens

Trigger: Emitting the input show action without .with_any("opt", input_opt), or double-taking the "opt" key so the value is gone when the TryFrom conversion runs.

Common situations: Plugins opening the input prompt by emitting raw actions; code paths refactored so another consumer drains the attachment first.
