Error message

Failed to create doc for editing

What it means

startEdit uses snapshotHelper.createStore(snapshot) to materialize a temp doc for comment editing; a null return means the store could not be created from the snapshot, so editing cannot start and this Error is thrown.

Solutions

1. Retry; ensure the workspace and doc service are initialized before editing comments.
2. Check storage/permissions for doc creation.

When it happens

Trigger: Thrown when startEdit in the comment entity cannot materialize a BlockSuite store from the comment snapshot, i.e. snapshotHelper.createStore returns null. Indicates a corrupted or incompatible comment content snapshot when beginning to edit a comment or reply.

Common situations: A user tries to edit an existing comment or reply whose stored snapshot is invalid or from an incompatible schema. Retry after reloading the doc; if persistent, the comment data may be corrupted and need re-creation.
