workspace cwd: %w

Error message

workspace cwd: %w

What it means

workspaceConfigHostPath calls ws.Cwd(ctx) to learn the workspace's current working directory so the config file path can be made workspace-root-relative. If that engine call fails, the error is wrapped with this prefix and returned to all path-dependent workspace operations.

Solutions

1. Inspect the wrapped cause for the underlying engine error and fix that (e.g. reconnect the engine).
2. Re-run the command to get a fresh engine session.
3. Verify the engine is healthy (`dagger query` with a trivial query) before retrying workspace operations.

if _, err := ws.Cwd(ctx); err != nil {
    // engine unreachable or session dead; reconnect before proceeding
    return fmt.Errorf("engine unavailable: %w", err)
}

path, err := workspaceConfigHostPath(ctx, ws)
if err != nil {
    if ctx.Err() != nil { return ctx.Err() }
    return fmt.Errorf("workspace cwd lookup failed; reconnect the engine and retry: %w", err)
}

When it happens

Trigger: Any install/uninstall SDK/module or env-write operation where the ws.Cwd() GraphQL call to the engine returns an error (engine failure, session terminated, workspace state unavailable).

Common situations: Engine session crashes mid-command, network/transport failure to the engine, or running against a remote engine where workspace cwd state cannot be fetched.
