What causes "escolha a pasta da biblioteca de destino" in tonhowtf/omniget?

Set `dest` to an existing library directory path in the UI/config before calling `run`

escolha a pasta da biblioteca de destino

Error message

escolha a pasta da biblioteca de destino

What it means

Thrown by SwitchAlbum's `run` when the destination field (`opts.dest`) is empty or whitespace-only. The tool requires an explicit target library folder so downloads from the card are never written to an unintended default location.

Solutions

Set `dest` to an existing library directory path in the UI/config before calling `run`
In the frontend, disable submit until the destination folder picker has a value
If invoked programmatically, pass the intended library root explicitly

Example fix

// before
SwitchOptions { source: card_path, dest: "".into(), mode: "copy".into() }
// after
SwitchOptions { source: card_path, dest: library_dir.into(), mode: "copy".into() }

Defensive patterns

Strategy: validation

Validate before calling

if dest.trim().is_empty() {
    return Err("destination library folder is required".to_string());
}
if !std::path::Path::new(dest.trim()).is_dir() {
    return Err("destination must be an existing directory".to_string());
}

Type guard

fn has_dest(opts: &SwitchOptions) -> bool {
    !opts.dest.trim().is_empty()
}

Try / catch

match switch_album::run(opts, progress).await {
    Ok(result) => handle(result),
    Err(e) if e.to_string().contains("biblioteca de destino") => open_dest_folder_picker(),
    Err(e) => return Err(e),
}

Prevention

Disable the submit button until a destination is selected
Persist the last-used library folder as a default
Trim user input and check non-empty before sending to the backend

When it happens

Trigger: Calling `run(SwitchOptions { dest: "", .. })` or `dest: " "` — any value whose `.trim()` is empty, regardless of source validity.

Common situations: Frontend form submitted without picking a destination folder; state reset cleared the dest picker; programmatic use omitted the `dest` field in the options struct.
