failed to get block: %w

Error message

failed to get block: %w

What it means

GetBlockJobStatus first fetches the waveobj.Block for blockId from wstore. This error wraps a DBGet failure for that block — a storage-layer error rather than a missing block (missing is reported separately as 'block not found').

Solutions

1. Inspect the wrapped inner error for the wstore cause
2. Retry with a valid context
3. Verify the wave DB integrity in the data directory
4. For event senders, skip sending the event on transient failure

Example fix

// before
status, err := jobcontroller.GetBlockJobStatus(ctx, blockId)
if err != nil {
	panic(err)
}
// after
status, err := jobcontroller.GetBlockJobStatus(ctx, blockId)
if err != nil {
	log.Printf("block job status unavailable for %s: %v", blockId, err)
	return
}

if ctx.Err() != nil {
	return errors.New("context canceled")
}
if blockId == "" {
	return errors.New("blockId is empty")
}

func blockExists(ctx context.Context, blockId string) bool {
	b, err := wstore.DBGet[*waveobj.Block](ctx, blockId)
	return err == nil && b != nil
}

status, err := jobcontroller.GetBlockJobStatus(ctx, blockId)
if err != nil && !strings.HasPrefix(err.Error(), "block not found") {
	log.Printf("transient failure for block %s: %v", blockId, err)
	return
}

When it happens

Trigger: Calling GetBlockJobStatus (directly or via SendBlockJobStatusEvent / BlockJobStatusCommand) when wstore.DBGet[*waveobj.Block] fails — DB I/O error, invalid/corrupted record data, canceled context.

Common situations: Querying a block while the DB is shutting down; corrupted block record; context canceled by an RPC timeout.
