Studio sequence selection is unavailable.

Error message

Studio sequence selection is unavailable.

What it means

The provided sequenceId does not match any sequence track in the current composition's timeline. Studio flattens <Sequence> components into tracks and looks the id up; no match throws this error.

Solutions

1. Use the MCP timeline listing to get valid sequence ids for the current composition
2. Add explicit id props to your <Sequence> components and use those exact strings
3. Verify the id is from the currently selected composition, not another one

const ids = getCurrentTimeline().map((t) => t.sequence.id);
if (!ids.includes(sequenceId)) { /* pick from ids */ }

catch (e) { if (e.message.includes('not found in the current composition')) { /* re-list timeline ids and retry with a valid one */ } }

When it happens

Trigger: Calling selectSequence with a typo'd id, an id from a different composition, or an id of a sequence not currently rendered in the timeline.

Common situations: Stale ids after renaming <Sequence id>, sequences nested inside compositions that are not the selected one, or hidden/collapsed tracks that are still addressable but with different ids.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
