The plugin was created, but no id was returned.

Error message

The plugin was created, but no id was returned.

What it means

createImportedPlugin POSTs the imported plugin and expects the response payload { item: { plugin: { id } } }. After the request succeeds (2xx) it extracts plugin.id; if the id is missing or not a string it throws this message. The plugin was actually created server-side — the failure is purely in reading the returned id, so retrying would duplicate the plugin.

Solutions

1. Inspect the create response in devtools/network to see the actual payload shape and fix the extraction path to match.
2. Align den-web and Den server versions so the create-plugin response contract matches.
3. Check for a proxy/middleware rewriting or truncating response bodies on /v1/plugins creation.
4. Before retrying, list plugins and reuse an existing plugin with the same name to avoid duplicates; make the server always return the id on success.

Example fix

// before: single rigid extraction path, duplicate-prone retry
const item = isRecord(result.payload) && isRecord(result.payload.item) ? result.payload.item : null;
const plugin = item && isRecord(item.plugin) ? item.plugin : null;
pluginId = plugin && typeof plugin.id === "string" ? plugin.id : null;
if (!pluginId) throw new Error("The plugin was created, but no id was returned.");
// after: accept alternate response shapes before giving up
function extractCreatedPluginId(payload: unknown): string | null {
  if (!isRecord(payload)) return null;
  const item = isRecord(payload.item) ? payload.item : payload;
  const plugin = isRecord(item.plugin) ? item.plugin : item;
  return typeof plugin.id === "string" ? plugin.id : null;
}
pluginId = extractCreatedPluginId(result.payload);
if (!pluginId) throw new Error("The plugin was created, but no id was returned.");

function validateCreatePluginResponse(payload: unknown): string | null {
  if (!isRecord(payload)) return null;
  const item = isRecord(payload.item) ? payload.item : payload;
  const plugin = isRecord(item.plugin) ? item.plugin : item;
  return typeof plugin.id === "string" && plugin.id.length > 0 ? plugin.id : null;
}
const id = validateCreatePluginResponse(result.payload);
if (!id) throw new Error("The plugin was created, but no id was returned.");

function isCreatePluginResponse(p: unknown): p is { item: { plugin: { id: string } } } {
  if (!isRecord(p) || !isRecord(p.item)) return false;
  const plugin = p.item.plugin;
  return isRecord(plugin) && typeof plugin.id === "string" && plugin.id.length > 0;
}

try {
  const id = await createImportedPlugin(draft);
  router.push(getPluginRoute(orgSlug, id));
} catch (err) {
  if (err instanceof MissingCreatedIdError) {
    const existing = await findPluginByName(draft.name); // avoid duplicate on retry
    if (existing) { router.push(getPluginRoute(orgSlug, existing.id)); return; }
  }
  showToast("The plugin may have been created but its id was not returned; check the plugin list.");
}

When it happens

Trigger: Server returns 200/201 with an unexpected payload shape: item missing, item.plugin missing, or plugin.id absent/non-string — typically a den-web/Den server API contract mismatch, a proxy stripping the body, or an empty 204 response.

Common situations: Self-hosted Den server version older/newer than den-web returning a different create-response envelope; a corporate proxy or auth wrapper rewriting the JSON; the endpoint changed from {item:{plugin:{id}}} to a flat shape; race where the response body was truncated.
