Cannot insert Element into this composition component

Error message

Cannot insert Element into this composition component

What it means

When planning to insert an Element, the target composition component is inspected for its canAddSequence capability. If the destination component does not allow adding a sequence (e.g. it is not a composition root that supports sequences), the plan fails with this error.

Solutions

1. Choose a destination that supports sequences (a composition component or new composition)
2. Check the target component with the sequence-capability API before calling the plan
3. Create a new composition as the destination instead of an existing unsupported component

const target = getInsertTarget(destination);
if (!target?.canAddSequence) {
  // pick another destination or create a new composition
}

const canInsertElement = (t: InsertTarget | null): t is InsertTarget => t !== null && t.canAddSequence;

When it happens

Trigger: Calling the Element install plan API (plan / getElementInstallPlanForProject) with a destination component whose target.canAddSequence is false, such as inserting into a non-composition component or an unsupported container.

Common situations: Trying to drag/drop or programmatically insert an Element into a nested component or a component that does not render <Sequence> children, or pointing at the wrong file in the destination.
