questions can only be generated for text chunks

Error message

questions can only be generated for text chunks

What it means

Type guard in RegenerateChunkQuestions: the requested chunk's ChunkType is not ChunkTypeText (e.g. a summary or table chunk). Question generation is only defined for text chunks; the input chunkID points at the wrong kind of chunk.

Solutions

1. Call the endpoint with a text chunk's ID
2. List chunk types first to select a ChunkTypeText chunk
3. Guard client-side against passing summary/table chunk IDs
