No composition is currently selected.

Error message

No composition is currently selected.

What it means

selectSequence requires Studio's sequence selection capability to be available (canSelect). If the current context does not support selecting sequences (e.g. the timeline/selection API is unavailable for the current composition), it throws.

Solutions

1. Retry after Studio is fully loaded and a composition is displayed
2. Ensure you are in the editor view where timeline selection is possible
3. Update Studio — selection availability depends on recent Studio versions

if (!canSelect) { /* wait for Studio editor to be ready, then retry */ }

catch (e) { if (e.message === 'Studio sequence selection is unavailable.') { await waitForReady(); await retry(); } }

When it happens

Trigger: Calling selectSequence when Studio cannot perform selection in the current mode, such as before the editor is ready or in a context where selection is disabled.

Common situations: MCP automation hitting Studio during startup or in a state where Visual Mode/timeline selection is not active.
