missing resource name in path %q

Error message

missing resource name in path %q

What it means

The selected path was non-empty but client.Namespaced(path) could not extract a resource name — the path is malformed, e.g. only a namespace ("myns") or a trailing-slash form ("myns/"). The name segment is required to build the kubectl edit target gvr.FQN(n).

Solutions

1. Inspect the selected row's Path column; fix the producer so it always sets path to ns/name (name from object meta.name).
2. Skip edit (and other row actions) for non-resource rows such as grouping headers.
3. If a custom column decorator builds the path, sanitize: strings.TrimSuffix(path, "/") and verify both segments non-empty.

Example fix

// before
row.Path = ns

// after
row.Path = ns + "/" + name

ns, n := client.Namespaced(path)
if n == "" {
    return fmt.Errorf("refusing edit: no name in path %q", path)
}

if err := editRes(app, gvr, path); err != nil && strings.Contains(err.Error(), "missing resource name") {
    slog.Error("malformed selection path", "path", path)
}

When it happens

Trigger: Path strings like "default/", "/", "ns-only", or paths with extra separators that make the name component empty. Produced by custom rows whose Path/ID column is populated from a field that lacks the name, or by a row representing a grouping/header node.

Common situations: Custom resource views where the ID column holds a namespace or label instead of ns/name; resources whose metadata.name is empty in the cached object; separators/dupes introduced by string joins in custom decorators.
