Question 1

Why am I getting a 'server error occurred' when loading a Next.js site that uses react-tweet?

Accepted Answer

A change in the react-tweet library can cause server errors because the tweet response body is missing required fields. The issue is tracked at https://github.com/vercel/react-tweet/issues/218. To fix, first update react-tweet to the latest version. If the error persists, apply a temporary workaround: patch the tweet data before rendering by adding missing fields like __typename, lang, and author. Check the issue for the exact shape needed. For example, ensure the response includes `__typename: 'Tweet'` and a valid `author` object.

Question 2

How to fix Rybbit MCP error -32602 'Output validation error: Expected number, received string' when calling get_goals?

Accepted Answer

This is a server-side type bug, not a client configuration issue. Postgres `count(*)` returns a bigint that Drizzle serializes as a string, but the MCP output schema for `get_goals` expects `meta.total` to be a number, so strict MCP clients (e.g. Cursor) reject the whole response.

Fix (self-hosted, in `server/src/api/analytics/goals/getGoals.ts`):

```ts
const totalGoals = Number(totalGoalsResult[0]?.count ?? 0);
```

Or cast in SQL:

```ts
.select({ count: sql<number>`count(*)::int` })
```

Also check other analytics list endpoints using the same `count(*)` → `meta.total` pattern, since they can fail MCP validation the same way.

Workarounds until the fix is deployed: call the HTTP API `GET /api/sites/:site/goals` directly and coerce `meta.total` with `Number()`, or fall back to raw event-count tools, which are unaffected.

Question 3

Why does Rybbit tracking return 404 "Site not found" when data-site-id contains only digits?

Accepted Answer

A digit-only newer text site `id` can be misclassified as a legacy numeric `siteId`, causing `/api/site/tracking-config/...` and `/api/track` to return 404. As a workaround, replace the dashboard-generated `data-site-id` with the smaller legacy numeric `siteId` from the site metadata, then reload the page. The permanent fix is for the backend to resolve the exact text `sites.id` first and fall back to `sites.siteId` only when that lookup fails.

Question 4

Why is the proxy code blank or missing in the Cloudflare Workers proxy guide?

Accepted Answer

This was an SSR/hydration bug in the docs Tabs component: the three `tabpanel` elements were rendered, but no `role="tablist"` tab triggers were emitted. The panels remained `data-state="inactive"`, hiding the code and collapsing the container. It is fixed in the current documentation. Hard-refresh the page with Ctrl+F5 (Cmd+Shift+R on macOS) or clear cached site data. If viewing an old/local docs build, update the docs and rebuild. As a temporary workaround, open DevTools → Elements, locate the hidden `tabpanel` elements, and remove the `hidden`/`data-state="inactive"` styling or set them to `display: block` to view and copy the code.

Question 5

Why do table columns resize when hovering over timestamps in the users view?

Accepted Answer

Known bug in v2.6.0 on Chrome. The column widths readjust when hovering over relative timestamps (e.g., "X minutes ago") as they expand to show the full date. This will be fixed in the next release. For now, avoid hovering or update when the new version is available.
