getting block info: %w

Error message

getting block info: %w

What it means

webGetRun resolves a block by --blockid and calls BlockInfoCommand over the wsh RPC. When the underlying RPC to fetch block info fails (block does not exist, connection to the Wave Terminal server failed, or permission/RPC error), the failure is wrapped with "getting block info:". This wrapper preserves the root cause so the CLI user can see why block metadata could not be retrieved.

Solutions

1. Verify the blockid is correct with `wsh ls` or by re-copying it from the Wave UI
2. Confirm the Wave Terminal app is running and the wsh client is connected (check WAVETERM_* env vars / connection)
3. Close and re-run the command against a still-open web block

if RpcContext == nil || RpcClient == nil { return errors.New("wsh not connected") }
// confirm block exists first: wsh ls

blockInfo, err := wshclient.BlockInfoCommand(RpcClient, oid, nil)
if err != nil {
    return fmt.Errorf("getting block info: %w", err)
}

When it happens

Trigger: Calling `wsh web get <selector> --blockid <id>` where the blockid does not resolve to an existing block, the wsh client is not connected to a running Wave Terminal, or BlockInfoCommand returns an RPC error (e.g. stale OID after the block was closed).

Common situations: Typing an invalid or truncated blockid; referencing a block that was closed; running wsh from a terminal without the WAVETERM connection context; the Wave app was restarted so block OIDs changed.
